A question I would have asked, experimentally, is were there any differences between the nominal bi guys and the nominal gay guys w.r.t. str8 porn.
But it is an interesting distinction to make about "men who are sexually and emotionally available to men" and those who are only "men who are sexually available to men." I look at it kind of like those guys you see in chatrooms or hookup sites who say "I don't kiss." They're looking for a sexual outlet only and they're ok with doing it with men (because, let's face it, men in general are just more open to more anonymous or "fuck buddy" sex than are women). Kissing involves more of an emotional connection. At least that's a theory anyway.
Is bisexuality real and distinctive from purely gay and purely str8? Well, I always thought so. I know men who say they engage in and enjoy sex with both sexes. And I know men who are not at all interested in sex with a woman.
I consider myself a gay man, yet I enjoyed oral sex and intercourse with my ex-wife. It was always pleasurable for both of us. I never saw it or viewed it as my husbandly duty or as something to be endured. Yet I cannot see myself in any future relationship with a woman.
