You have an excellent service and give great advice. That is why I feel comfortable asking you this question. About three weeks ago, a group of my friends and I went out to a movie and then a club where we each had some alcohol. After the club, we went back to a friend's room where the group gradually dispersed until there was only myself, two male friends, and one female friend. We began to play sex games. Eventually, we all were naked, on my friend's bed. The female of the group was the center of our activity. She seemed to want it and even encouraged what the three of us started doing to her.

Although we all were tipsy, it was a great sexual experience for all of us, or so I thought. My two male friends have no problem with what happened. The only thing is that my female friend won't speak to us or return any of our calls. I saw her walking down the street the other day and tried to talk to her, but she wouldn't even raise her head to look me in the eye. Do you have any idea what is wrong? Could my friend feel that she was raped? I want to apologize, but I'm not sure what to do.

Every time I have an orgasm (alone or with a partner) I have intense feelings of guilt. I was not brought up in a religious household and was never told to "wait until marriage". I've been in long term relationships with all my sexual partners so it's not like I feel guilty for sleeping around. It's getting to the point where I'm not enjoying sex anymore because I dread the feelings I have after an orgasm. Is this normal?

I have a problem that is really uncomfortable for me to deal with, but I'm embarrassed to ask anyone if they have had the same experience. Whenever I take an exam, I sometimes ejaculate in my underwear. I think it may be some sort of stress reaction. Once it's over, I feel very calm and can continue on. Is something wrong, and how common is this? What should I do?

When I get excited about going to see the boy I love or nervous about hanging out alone with him, I have to poop. Everytime. My stomach gets really upset and it cramps and then I have to poop. In most cases it's diarrhea and I never feel like I'm okay by the time I have to leave. Is there something I can do about it to limit it or just stop it in general? I love knowing that I get to see him but I hate the baggage I get beforehand.

Do you believe in going from one relationship that did not work to another, without regrets? How come some people can change their lives without looking back? Is it possible to grow old without regrets?

I've had sex and I really wish that I'd never done it. I didn't really enjoy it, either. It really hurt and I said I'd never do it again. Will I enjoy it next time?
