I had my first sexual experience with my girlfriend a few months ago. She told me she was a virgin, but after having intercourse, I didn't believe her and was hurt. She didn't seem to be in any pain, there was no bleeding, and there was no hymen. She makes up all these excuses like "not all girls have them." Should I believe her? Is there a sure-fire way of determining whether or not I was her first? It is making me angry. Can you ease my pain?

I am afraid my need for sexual attention is getting out of hand. The past several weekends I have wound up kissing guys in bars, and I find myself less interested in flirting or having interesting conversations with them than I am in getting that rush of meeting someone new. This weekend I had sex with a guy I had just met in a bar and I have no idea why. Making matters worse is that he was much younger than I am and I don't think we had anything in common whatsoever. I feel like I am devaluing myself and I don't want to lose my self-respect. How can I find the cause of my behavior and how can I stop?

I was wondering if there was any way that a hymen can be replaced by plastic surgery? I am not a virgin and will marry an Arab man who will expect his wife to be a virgin during the wedding. I know this must sound a little odd but I really need your help!

I grew up in a religiously conservative family, and now I go to a private Christian college. I will be a junior this year, but I've known since freshman year that the school and the religion just weren't right for me. I love the education, but I'm afraid I'm sexually deprived. When I hear all my friends who go to public school talk about parties and sex, it makes me feel like I'm really missing out. I wanted to transfer, but it just isn't fiscally possible. I'm a very mature person, but I haven't done anything sexual (not even kiss!). The girl to guy ratio at my school is 3:1, and most of the boys are very awkward. I want to experiment, but no one at my school does that. I'm afraid that when I graduate, I still won't have done anything, and no one will want me because I have no experience.

I'm a Christian, very conservative in upbringing, and I'm having difficulties in discussing sex in an open and casual manner. I told my male friends that sex should be done within the parameters of marriage. But they told me that I should have a first sexual experience so as to satisfy my wife or maybe a girlfriend (I don't have one yet). Should I follow their opinion regarding this? Should I first know the sexual dynamics of sexual intercourse before doing it with her?

I would appreciate your kind response.

Thank you.
