For oral sex on a man, use a condom during oral sex. For oral sex on a woman, or when performing anilingus on a man or a woman, use a dam. A dam is a small thin latex or plastic square that acts as a barrier between the vagina or anus and the mouth. It may prevent the spread of STIs. You can buy dams at some sexual health clinics, online or at your pharmacy.
^ Ken Plummer (2002). Modern Homosexualities: Fragments of Lesbian and Gay Experiences. Routledge. pp. 1920–1921. ISBN 1134922426. Retrieved August 24, 2013. The social construction of 'sex' as vaginal intercourse affects how other forms of sexual activity are evaluated as sexually satisfying or arousing; in some cases whether an activity is seen as a sexual act at all. For example, unless a woman has been penetrated by a man's penis she is still technically a virgin even if she has had lots of sexual experience.
Links have been reported between oral sex and oral cancer with human papillomavirus (HPV)-infected people. A 2005 research study suggested that performing unprotected oral sex on a person infected with HPV might increase the risk of oral cancer. The study found that 36 percent of the cancer patients had HPV compared to only 1 percent of the healthy control group.
Fellatio is sometimes practiced when penile penetration would create a physical difficulty for a sex partner. For example, it may be practiced during pregnancy instead of vaginal intercourse by couples wishing to engage in intimate sexual activity while avoiding the difficulty of vaginal intercourse during later stages of pregnancy. There may be other reasons why a woman may not wish to have vaginal intercourse, such as apprehension of losing her virginity, of becoming pregnant, or she may be menstruating.
You and your man should be facing each other on your sides, superclose together, says Paget. Raise your upper leg and help him to slide inside you, then drape the leg over his and tight around it. "Try to arrange it so that your feet are braced against a wall or footboard," she advises. "That way, you can use the strength in your feet, legs and toes to give you the action you want." If you tend to get tense before climaxing, this is the perfect move to do as you peak upward. "Some women require a form of strong muscular contraction to get to that next level of stimulation that leads to orgasm," says Paget. "The side-by-side allows you to have that firm, full-body contraction while staying in motion." Adjust the coital fit of his entry by tensing or relaxing your thighs together. You'll hug his trunk, stimulating the inner walls of your entire vagina; by relaxing your legs and opening them somewhat, he'll have a bigger range of motion, which can help you get intense clitoral titillation en route to your climax.
