I am a lesbian. Being with men never felt right. I always felt too self conscious and with a woman I am more at ease and feel way more sexy. I am also very much more turned on than when I was with a guy!
Coming from a gay guy (I see there are more women posting here lol), I have a deeper emotional connection with guys. I have tried the bisexual thing and well me and the ladies in a relationship... it just never ends well. We always end up fighting, the lack of emotional connect is very obvious... And with women I have a lack of sexual interest as well as a lack of attraction all together.
HOWEVER I get along with the ladies as far as friendship goes.
What makes you prefer the gender you prefer? I like girls more because they seem to understand me and my body better then guys do.
I like both, with a very slight lean towards women. It probably mostly comes from the more natural feeling (to me) of vaginal penetration. I think it's mostly an innate thing with me, something I can't explain a whole lot more than I have. But everythings good :]
I find that gender doesn't really influence my attraction to people. I find myself liking and being attracted to trans* people, women, and men - it just depends more on the individual than it does on their gender for me.
I prefer women because they seem to empathize more with my past, and they are less jealous and possessive. However, I date men more because it's often more convenient and I pass as straight so it just happens that way unfortunately.
