Oral sex and mutual masturbation are more common than anal stimulation among men in sexual relationships with other men. According to Weiten et al., anal intercourse is generally more popular among gay male couples than among heterosexual couples, but "it ranks behind oral sex and mutual masturbation" among both sexual orientations in prevalence. Wellings et al. reported that "the equation of 'homosexual' with 'anal' sex among men is common among lay and health professionals alike" and that "yet an Internet survey of 180,000 MSM across Europe (EMIS, 2011) showed that oral sex was most commonly practised, followed by mutual masturbation, with anal intercourse in third place".
