I have been dating a guy for well over a year-and-a-half, and we really enjoy each other's companionship. We have a great friendship and a great sex life. The problem is that I am finding myself attracted to another person. I think this other person has a girlfriend. Furthermore, I don't want to have a relationship with this other person — it's just that I find myself dreaming about kissing him because he is so attractive. I know I'm crazy because everything is great in my relationship and people envy the relationship I have with my boyfriend. I just can't get this guy off my mind. What should I do?

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?

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!

Just a quick question: why is it that nice guys always finish last? I've tried being nice all my life (nineteen years) to women, yet I get nothing. Yet if some guy who treats them really badly comes in, they're the ones who end up with a girlfriend — and me with squat. What's the deal?!

I recently met this guy who is amazing. We get along very well. I really like him, and I would love to have a relationship with him, but I found out that he has pancreatic cancer and only has three to five years to live. I just really don't know what to do. I think it would be considered screwing myself over by getting emotionally involved with someone who is going to die soon. But, I also feel for him, and I think everyone should have a chance at love. What should I do?
