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've been gay all of my life, and until just now, I've learned to accept it. I've told all my friends that I am gay. Some of them didn't like that, and now they're not my friends. None of my other friends are gay, which was a disappointment because I had a crush on one of them. Now I don't know what to do because not only do I not know who else is gay, but I don't have the courage to ask someone out. I'm afraid that if I can't ask someone out by the time I'm out of college, I'll never be able to have a relationship. I don't want to have to resort to online dating either. I want to know how I can overcome my fear.

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?
