I believe women are more interested than men. For instance, a woman raised the issue here.
In my experience, that issue has always been raised by the woman.
None of them were dismissive, all of them curious.
Homosexuality, or heterosexuality for that matter, seems to be more involved with the sexes with the participants rather than the particular activity.
I don't think there's any question that sexuality is determined by DNA. Too many homosexuals have tried to go straight and failed. And as for myself, homosexuality is so personally offensive as to be impossible. And I've worked with enough homosexuals to know their relationships are exactly like heterosexual relationships.
So who is going to be the last to say people can't love each other?
