Should I tell my friend that I'm worried about how she sleeps around?

My friend has only been at college for two weeks, and she has already had sex with several guys. She is having safe sex, so it's not dangerous in that sense and she claims to be enjoying herself. However, it seems to me that such behavior is unhealthy and damaging to one's emotional state and reputation — but I'm not sure how to explain to her how I feel, or articulate what is wrong with her how she's acting. Do you think what she's doing is wrong, and if so, how should I confront her?


How can I get over the awkwardness after telling my friend I like him?

I'm very attracted to one of my close friends. He used to like me and I used to like him. The other day, I told him I still liked him and that it'd be cool if we took our friendship further. But he just said he liked me as a friend. However, many of my friends have been telling me that he likes me more than a friend and that we'd be good together. After telling him how I feel, I think that he doesn't even want to be friends now, plus he is really awkward. How can I get our friendship back and break the awkwardness? How can I make sure I don't get rejected again by someone else?


What are the common reasons for condom failure?

I live in Prague, Czech Republic — Europe. Before asking any question, I should tell you that I really appreciate your service. As for my question, I would like to ask you about the most common reasons for condom failure as a contraceptive method. I suppose that the most frequent one is condom breakage. But what are the others? I am especially concerned about pregnancy risk implied by the accidental transfer of sperm in pre-cum to condom by fingers while putting it on.
