Is it possible to find female PSA, or other types of sexual fluids on another female? For example, if there was a case of women on women rape, could it be possible to find the woman's DNA on the victim? Like when they find semen on victims?

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.

How is food addiction similar to drug addiction?

I was wondering what the main reason is behind women getting sexually assaulted. Is it because of the way they dress, the way they act, or how easily tricked they are? Do girls say something provocative that entices the male to engage in sexual assault?

In the beginning, I told my boyfriend that I don't want to have sex outside of marriage and he accepted that.

But then, about a week ago, I made a very big mistake and allowed him to take my clothes off completely and enter my vagina slightly. I know it was wrong and the following day I told him that I didn't feel right about it and I didn't want us to do that again.

Unfortunately, the very next day, we were alone together, and we got a bit carried away again. But when he tried to "enter" me, I said: "I think we should stop now, let's stop — ok? Please, let's stop now. I don't feel right about this." But he didn't... he spread my legs anyway and got on top of me. And he penetrated me quite deeply. As he was doing it, I was saying, "Stop, please, I really think we should stop," but I didn't push him away. I didn't physically PUSH him or something to make him stop.

I was quite shook up afterwards but I didn't know if I should be angry with him or not. We are still together and I don't even think he thinks he did anything wrong... DID he do anything wrong? Or is what he did alright because my body wasn't saying "no"? I didn't fight him physically. Do you think I was raped? I'm so confused and I've lost all my self-respect!

I am a college freshman and I think I'm on my way to becoming bulimic. Since my junior year of high school, I have periodically binged and tried to purge, but I was never really successful and it was never frequent. My senior year I made myself semi-successfully throw up for the first time, but it was gross and scary and made my throat bleed and I stopped. However, since I've gotten to school this year, I feel like things have gotten out of control. I started out eating healthfully and losing weight, because I am about 15 pounds overweight and need to make a lower weight class for my sport. (I am at a high level and compete internationally.) I'm also terrified of the "freshman fifteen" since I've always been chubby at the least. I couldn't keep up my healthy eating and snapped, and now I binge all the time and for the past few weeks have been throwing up. I think I could stop but I'm not sure. Am I bulimic or just going through typical freshman food phase?

Thanks for any advice.

I have three young daughters (ages 8, 6, and 3 years), and I know that it is about time to begin teaching them and talking to them about sexual issues. But my mother never talked to me about such things, so I really don't know where to begin. I do need to do it soon, though, because I was molested as a child and I don't want my girls to go through the same thing, you know, thinking they have no one to talk to about such things. Because my Mother never believed me when I told her that someone had molested me, I want my girls to be able to talk to me about anything. But I am very shy and easily embarrassed by certain issues, such as sex. How can I overcome this, and how do I spark a conversation about sex with a six-year-old, what should or shouldn't she know, and how can I explain things so she will understand? Same thing for the three-year-old.
