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 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 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?

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.
