Well, I'm not a male, but since no one else has responded, then I will put my two cents' worth in. I do know of at least two males who had some sexual encounters with other males (oral sex), although they identify as heterosexual.

It is possible for someone to be asexual. Maybe your sex drive is not as active as some folks. But if you spend a lot of time with one person, then the needs are more likely to make you attracted to that person.
