Please do not be offended by this question

I have several friends who are gay, both male and female. My question is. Why do some woman that are gay dress and act like men, but don't want to be with one and same for men who are gay, some act more feminine. But don't like women. I don't mean this to be offensive in any way at all.

    I will ask them when I see them on vacation. i know they wont be offended but I would rather ask in person. Nature verses nurture makes sense to me.
