I'm still so confused about my sexuality, which is even more confusing that I'm 32 now...

I love women and currently I don't want to date guys at all. But I've been falling in love with guys for a really long time. I believe this love was genuine. However, when I think about my sex life with men, I feel that most of the time, I did to be loved in return, to be nice with them, or because I thought it was something I owed them because they put a certain effort in the relationship. I orgasmed with them but only if I was thinking about a woman.

I really don't know why I don't want to be touched by them anymore. Is it because I had poor experiences with them? Or because I can love them (kiss them, smell them...) but not be attracted to them sexually?
