Other aspects of the adult industry include phone sex operators, strip clubs , and pornography. The relation between gender equality and sexual expression is recognized, and promotion of equity between men and women is crucial for attaining sexual and reproductive health , as stated by the UN International Conference on Population and Development Program of Action: [53]. BDSM is a variety of erotic practices or roleplaying involving bondage , dominance and submission , sadomasochism , and other interpersonal dynamics.

Given the wide range of practices, some of which may be engaged in by people who do not consider themselves as practicing BDSM, inclusion in the BDSM community or subculture is usually dependent on self-identification and shared experience. BDSM communities generally welcome anyone with a non-normative streak who identifies with the community; this may include cross-dressers , extreme body modification enthusiasts, animal players , latex or rubber aficionados , and others.

Bondage includes the restraint of the body or mind. A submissive is someone who gives up the control to a person who wishes to take control. Masochism means an individual who takes pleasure from their own pain or humiliation. Unlike the usual "power neutral" relationships and play styles commonly followed by couples, activities and relationships within a BDSM context are often characterized by the participants' taking on complementary, but unequal roles; thus, the idea of informed consent of both the partners becomes essential.

Participants who exert sexual dominance over their partners are known as dominants or tops , while participants who take the passive, receiving, or obedient role are known as submissives or bottoms. Individuals are also sometimes abbreviated when referred to in writing, so a dominant person may be referred to as a "dom" for a man or a woman. Sometimes a woman may choose to use the female specific term "Domme".

Both terms are pronounced the same when spoken. The precise definition of roles and self-identification is a common subject of debate within the community. In a study, the researchers state that BDSM is a sexual act where they play role games, use restraint, use power exchange, use suppression and pain is sometimes involved depending on individual s.

According to the findings, one who participates in BDSM may have greater strength socially and mentally as well as greater independence than those who do not practice BDSM. Before any sexual act occurs, the partners must discuss their agreement of their relationship. They discuss how long the play will last, the intensity, their actions, what each participant needs or desires. The sexual acts are all recorded as consensual and pleasurable to both parties.

In a study, interviewed BDSM participants have mentioned that the activities have helped to create higher levels of connection, intimacy, trust and communication between partners.

The participants have remarked that they enjoy pleasing their partner in any way they can and many surveyed have felt that this is one of the best things about BDSM.

It gives a submissive pleasure to do things in general for their dominant. Where a Dominant enjoys making their encounters all about the submissive. They enjoy doing things that makes their submissive happy. The participants have also mentioned improvements in their personal growth, romantic relationships, sense of community and self, the dominant's confidence, and their coping with everyday things by giving them a psychological release.

There are many laws and social customs which prohibit, or in some way affect sexual activities. These laws and customs vary from country to country, and have varied over time. They cover, for example, a prohibition to non-consensual sex, to sex outside marriage, to sexual activity in public, besides many others. Many of these restrictions are non-controversial, but some have been the subject of public debate.

The details of this distinction may vary among different legal jurisdictions. Also, what constitutes effective consent in sexual matters varies from culture to culture and is frequently debated. Laws regulating the minimum age at which a person can consent to have sex age of consent are frequently the subject of debate, as is adolescent sexual behavior in general. Some societies have forced marriage, where consent may not be required. Many locales have laws that limit or prohibit same-sex sexual activity.

In the West, sex before marriage is not illegal [ example needed ]. There are social taboos and many religions condemn pre-marital sex. Those found guilty, especially women, may be forced to wed the sexual partner, publicly beaten, or stoned to death. Other studies have analyzed the changing attitudes about sex that American adolescents have outside marriage. Adolescents were asked how they felt about oral and vaginal sex in relation to their health, social, and emotional well-being. The laws of each jurisdiction set the minimum age at which a young person is allowed to engage in sexual activity.

In many jurisdictions, age of consent is a person's mental or functional age. Age of consent may vary by the type of sexual act, the sex of the actors, or other restrictions such as abuse of a position of trust. Some jurisdictions also make allowances for young people engaged in sexual acts with each other.

These laws vary to some extent; such acts are called incestuous. Non-consensual sexual activity or subjecting an unwilling person to witnessing a sexual activity are forms of sexual abuse , as well as in many countries certain non-consensual paraphilias such as frotteurism , telephone scatophilia indecent phonecalls , and non-consensual exhibitionism and voyeurism known as " indecent exposure " and " peeping tom " respectively. People sometimes exchange sex for money or access to other resources.

Work takes place under many varied circumstances. The legal status of prostitution varies from country to country , from being a punishable crime to a regulated profession.

Retrieved 28 February Archived from the original on 21 July To obtain the deepest penetration in this sex position, the woman should keep her feet firmly on the floor throughout sex, for as soon as she raises her feet or stretches out her legs, the vaginal angle changes and penetration immediately becomes shallower.

Some modern beds are low enough that they permit intercourse in another face to face sexual position; here again the woman lies across the bed, her buttocks on its edge and the man kneels between her legs.

If his pubic area is below her he must kneel on something - pillows or a footstool, or whatever is convenient and of the right height - to bring it level with hers. Having got as close to the bed as he can he places his hands under her thighs and draws her vagina on to his penis. She then raises her legs until they rest on his hips, and if possible crosses her ankles behind his back. He supports her thighs with his hands throughout sex.

The woman lies lengthways on the bed - i. Again supporting the woman's buttocks with his hands, he works his way forward until his knees are right under them and her vagina entrance is above his penis.

He then lowers her vagina over his penis. In this position the woman must make the movements, which should not be so great that the penis, once in, leaves the vagina. As a variation on this, and depending on the suppleness of the woman's legs, she can raise one leg at a time, so that eventually her heels rest on her man's shoulders. Or she may only so raise one leg; or during intercourse, she may alternate them.

Whichever she does, she increases penetration. This posture can be taken up when the woman lies across the bed and the man kneels on the floor. None of these postures is per cent successful when the vaginal entrance is set forward.

If, however, it is set back, they are really ideal. Without doubt the greatest sensations of deep penetration, and actual deep penetration, are provided by the next sexual position. Let's not forget that good lovemaking depends on a fully rounded and balanced personality in each partner, including a well-developed lover archetype in men. You can read about this here: king warrior magician lover. We've always tried to avoid the images that offend by including only tasteful pictures of lovemaking from men and women in committed relationships, showing the joy and delight of sex in the context of an equal relationship between the male and female partner.

From the female forums , where comment is, as they say, free! Question: I'll keep this simple - What is the best sex position, do you think, to get the deepest penetration? But anal can feel good if you have a partner who knows how to do it and uses lots of lube. Two variations which will produce totally different sensations: first is rear entry with the woman on her hands and knees or maybe standing up as she bends over so he can enter from behind - it is best to have something to hold on to as this allows you to push back a little as he thrusts - this position can even be enjoyed in the shower Enjoy - I know I do!

I then rock or lift her backwards so that her buttocks are raised off the bed. At this point I push deep into her pussy. A variation is to have her legs on my shoulders and put my hands under her hips, then lift her up towards me and onto my cock. As I lean forward, I'm above her at a steep angle, and I can push deeply into her. As I thrust with my pelvis I pull her towards me with my arms wrapped around her. All these positions are good for us. I also agree that for my man penetration seems to feel deeper when my legs are pressed or somehow pinned back.

Also I feel I have better vaginal muscle control in this position, which means I can squeeze and relax around his penis when he enters me from behind. This feels so great, but of course it may be psychological! And sex in the "from behind" position always feels great as well! That way he can get deep - and boy does it feel good! Doggy style just doesn't go as deep for me - maybe something to do with the angles? Experimentation is the best way to find out!

I find riding my man is the best way not only to be in control - but also to get deep into me, since I can press down very hard and he can push up; another bonus is I always cum this way! Woman on top is also good when I have my legs up to his shoulders, but I find it tiring. For anyone over fifty, this sex position may not be so good.

Rear entry sex doesn't work for me. I like man on top or missionary position, with my legs very wide and my hips lifted up on a pillow or cushion.

In this way, my head and shoulders are flat on the bed, hips and bottom lifted high. He can plumb my depths during sex! These positions make it easier for me to control my vaginal muscles this way and I can really squeeze my vagina on his cock and even move my clitoris up.

G'Day All, I'm a 19 year old male from Australia and have a strange question. My penis size is about 7 inches not too bad I think and I wonder if a women could take it all, so my question is, how deep is a woman's vagina? It's hard to understand where the penis goes, because a 7 inch one for example usually has no problem in this area, at least with me.

However, my man is 11 inches long when erect, so I tend to avoid all the sexual positions described above. I sometimes take him - but it hurts a little. A good one is to have him lying on his back on the bed and for me to lie on top of him, facing the same way upwards! Another deep penetration position for sexual intercourse I'm not sure if anyone mentioned it is missionary with my legs on his shoulders. Editor's note: The average vagina is about four inches when resting and unaroused - and up to six when its owner is sexually aroused - but the penis slides under the cervix during intercourse because the uterus is pulled upwards when a woman is lying on her back so the vagina is effectively longer than six inches in this position at least.

I just get my partner to lie on her side, then I mould myself to her back so that my front is against her back in the typical spoons position. I then prop open my top leg up with my foot on the bed and she and rests her top leg on my top leg, that has the bonus of opening her vulva up wide and so I am able to enter her and, joy of joys, I can also reach around with my hand and massage her clit as I fuck her. It is better than doggy style because doggy is sort of thrusting straight in and out.

And what we've found is that we can produce squirting orgasms when we do this! I find this feels much deeper than rear entry sex This means I can go pretty deep.

Unlike rear entry sex, it also allows you to pleasure your woman by kissing her or touching or sucking and kissing her breasts.

My girlfriend doesn't like doggy style sex because of that problem. I am sitting with my feet on the floor, or lying back on the bed with my feet on the floor we enjoy both variations , at the corner of the bed with him standing in front of me, then he raises my legs and pushes inside.

This lets him go deep and he pushes with his legs to get extra power into his thrusts and fills me full I think he just stretches me so wide that it produces such a full feeling I lean towards his feet and then hold onto the lower part of his legs near his ankles. I can control how fast we make love and deep he goes into me and of course he gets to enjoy looking at me from behind. When we're just about on the point of cumming I sit myself up straight and it then feels like his penis goes right through me I want him to go into me as far as he can.

I don't know how to choose the best sex position for me so this is a helpful thread. Rear entry positions, and man on top with legs on the shoulders are undoubtedly the best ways to achieve full penetration. Of course that feels good, and there's nothing better than thrusting balls-deep into tight, wet, hot pussy.

[Penetration of microparticles into human skin].

In a previous study we demonstrated that human vaginal mucosa was as permeable to water as was buccal mucosa. Water, however, is a very small molecule with a molecular weight of 18 d.

To further explore similarities between these two types of mucosa with respect to permeability, it was decided to investigate the passage of two large, hydrophilic molecules across these epithelia. Specimens of fresh, clinically healthy human vaginal and buccal mucosa were taken from excised tissue obtained during vaginal hysterectomies and various oral surgical procedures. Seven biopsy materials from each specimen were mounted in flow-through diffusion cells exposed area, 0. Dextran was detected by means of a fluorospectrophotometric method at excitation and emission wave lengths of and nm, respectively.

Specimens were examined histologically before and after permeability experiments, and similarities between vaginal and buccal tissues were verified. No statistically significant differences between the flux values of the 4.

However, for the kd dextran the flux rate across buccal mucosa was significantly higher than the rate across vaginal mucosa. This further supports the hypothesis that vaginal mucosa may be a useful model for studying the passage across buccal mucosa of chemical compounds and therapeutic agents that are less than approximately 4. For a kd dextran the flux rate across buccal mucosa is significantly higher than the flux rate across vaginal mucosa, and the model becomes inaccurate.
