Deep, couldn't agree with you more. I, a pure(?) gay guy, have all along been confused about bi-sexuals and maybe still am. Have come across guys who are interested in the sole satisfaction of the organ between their legs, completely ignoring the needs of their partners. Maybe in many cases of man-woman sex , the man plays with the female body, makes love to it. The woman, because she is taught not to express her desire or not taught to express her desire, does not play with/ pay attention to the man's body. This attention/ appreciation is what this man gets when he sleeps with a gay guy.
I translate from an article by Dulari Deshpande : (http://www.lokprabha.com/20120203/samarthincha-sampraday.htm) "Many men from the 'straight' society, who are married to 'straight' women, have sexual relations with gay men. Some of these men could be bisexuals, but not all. Some straight men have sex with gay men for the sake of variety in sex. These should really be called perverts. The attraction gay men have for other men is both physical as well emotional. These perverts, men from straight society who have relation with gay men for sexual satisfaction, are only taking undue advanatge of the gay tendencies of their gay partners." This is what she says about gay men getting into marriage with straight women : "Under pressure from family/society and the false hope that 'it' may change post marriage, some gay men marry a straight woman. They start having sex with the woman, but soon get tired off it. Their natural tendency makes them search for gay partners. Once they find such partner, they start living a dual life; enjoying the social status/security of being married to a straight woman and also secretely enjoying sexual life with gay partner. Some such marriages end in divorce, devastating not just two human beings but two families. By the way, just like men , could some women be bisexuals?
