Gay sexual practices are sexual activities involving men who have sex with men (MSM), regardless of their sexual orientation or sexual identity. The authors of the Kinsey Reports state that 37% of their male subjects had at least one homosexual experience.〔Sexual Behavior in the Human Male, p. 656〕 Evidence shows that sex between men is significantly underreported in surveys due to social desirability bias. ==Activities== Historically, anal sex has been popularly associated with male homosexuality and MSM. However, many MSM do not engage in anal sex, and may engage in oral sex, frottage or frot, or mutual masturbation instead. MSM may also engage in different forms of oral sex, such as fellatio, tea bagging, and anilingus. Wellings et al. reported that "the equation of 'homosexual' with 'anal' sex among men is common among lay and health professionals alike," whereas an online survey of 18,000 MSM in Europe "showed that oral sex was most commonly practised, followed by mutual masturbation, with anal intercourse in third place."〔 A 2011 survey by ''The Journal of Sexual Medicine'' found similar results for U.S. gay and bisexual men. Kissing a partner on the mouth (74.5%), oral sex (72.7%), and partnered masturbation (68.4%) were the three most common behaviors, with 63.2% of the sample self-reporting 5-9 different sexual behaviors during their last encounter.〔(Sexual Behaviors and Situational Characteristics of Most Recent Male-Partnered Sexual Event among Gay and Bisexually Identified Men in the United States ) onlinelibrary.wiley.com Retrieved 2-13-2014〕 Among men who have anal sex with other men, the insertive partner may be referred to as the ''top'', the one being penetrated may be referred to as the ''bottom'', and those who enjoy either role may be referred to as ''versatile''.〔 Pleasure, pain, or both may accompany anal sex. While the nerve endings in the anus can provide pleasurable feelings, an orgasm may be achieved through receptive anal penetration by indirect stimulation of the prostate. A study by the National Survey of Sexual Health and Behavior (NSSHB) indicated that men who self-report taking a receptive position during anal sex in their last encounter were at least as likely to have reached orgasm as men who adopted an insertive role. A study sampling single people in the U.S. indicated that orgasm rates are similar among men across sexual orientations. With regard to pain or being uncomfortable during anal sex, some research indicates that, for 24% to 61% of gay or bisexual men, painful receptive anal sex (known as anodyspareunia) is a frequent lifetime sexual difficultly.〔 Reports with regard to the prevalence of anal sex among MSM have varied over time, with some percentages higher than others.〔Laumann, E., Gagnon, J.H., Michael, R.T., and Michaels, S. The Social Organization of Sexuality: Sexual Practices in the United States. 1994. Chicago: University of Chicago Press (Also reported in the companion volume, Michael et al., Sex in America: A Definitive Survey, 1994).〕〔Center for Disease Control, ''Increases in Unsafe Sex and Rectal Gonorrhea Among Men Who Have Sex With Men – San Francisco, California, 1994–1997''(). Retrieved April 29, 2007.〕〔(【引用サイトリンク】publisher=WebMD )〕 A large percentage of gay and bisexual men self-report lifetime participation in anal sex.〔 Studies among gay men have indicated that percentages are similar when comparing men who prefer to penetrate their partners to those who prefer to be the receptive partner.〔 Some men who have sex with men, however, believe that being a receptive partner during anal sex questions their masculinity. With regard to non-penetrative sex, there is also variety. Frot is a form of male-male sexual activity that usually involves direct penis-to-penis contact. It is a form of frottage. Frot can be enjoyable because it mutually and simultaneously stimulates the genitals of both partners as it tends to produce pleasurable friction against the frenulum nerve bundle on the underside of each man's penile shaft, just below the urinary opening (meatus) of the penis head (glans penis). Intercrural sex is another form of non-penetrative sex that can be practiced between MSM. Docking (the insertion of one man's penis into another man's foreskin) is also practiced. MSM may engage in BDSM or use sex toys. A study done from 2001 to 2002 in Australia found that 4.4% of gay men and 14.2% of bisexual men participated in BDSM-related sexual activities in the 12 months prior to the survey.〔 Richters, J., De Visser, R. O., Rissel, C. E., Grulich, A. E., & Smith, A. (2008). Demographic and psychosocial features of participants in bondage and discipline, "Sadomasochism" or Dominance and Submission (BDSM): Data from a National Survey. The journal of sexual medicine, 5(7), 1660–1668.〕 A non-representative survey on the sexual behavior of American students published in 1997 and based on questionnaires found 24% of the gay and bisexual men had experience with spanking as a sexual practice.〔 Elliott, Leland / Brantley, Cynthia, Sex on Campus, 1997, Random House, New York〕 Among medicine students in North America, 6% of gay men and 17% of bisexual men reported ever receiving pain for sexual pleasure, and 5% of gay men and 9% of bisexual men reported inflicting pain for this purpose.〔 According to an online survey of over 25,000 men who self-report a homosexual or bisexual orientation, 49.8% have ever used vibrators. Most men who had used a vibrator in the past reported use during masturbation (86.2%). When used during partnered interactions, vibrators were incorporated into foreplay (65.9%) and intercourse (59.4%). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gay sexual practices」の詳細全文を読む スポンサード リンク
