Men, both gay and straight, can enjoy the intensely pleasurable sensations of anal penetration, when combined with appropriate lubrication and a sensitive lover. But usually male orgasm still relies on penile stimulation. Homosexual erotic fiction indicates that anal sex becomes uncomfortable for the receiving male if he loses his erection. Women only start to have erections (of the internal clitoral organ) in late middle age.
The heterosexual focus on intercourse is not just a matter of convention. Men are biologically programmed to prefer intercourse otherwise men could engage in oral sex or masturbation instead and none of us would be here to talk about it. Consequently most men cannot accept that women's responsiveness is so different to how it is portrayed in fictional media.
