I have been on the Nuvaring for three months now, and I am keeping it in for the four weeks then changing it because my doctor said there's no need for me to have a period. About two weeks ago I started having dark brown discharge and it has gotten more heavy, but only when I run or stand up real quick. Is this normal or should I call my doctor and find out what is going on?

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.

PLEASE, PLEASE, PLEASE answer this question for me. Are condoms you buy from machines in the bathroom safe? What I mean is, could they carry some sort of disease or STD or anything that can make me sick (I don't mean allergies)? And also, could you tell me if American condoms are better than other countries' condoms? I read that U.S. condoms are electronically tested for defects or diseases, but I was wondering if other countries like Europe or Thailand or whatever tested their condoms, too. If I was older, I would buy condoms from boxes, but until then, I am stuck buying them from bathroom machines.

My boyfriend says that he doesn't enjoy oral sex with me because of the taste. He says it's too strong. I have had 2 pap smears in the last year and my doctors say everything is fine and tell me not to douche. I need to do something. This has caused a lot of problems in our sexual relationship. Can my diet or anything else help this problem?

Help me!!! I've put the condom on backwards when we were drunk and then turned it the right way round. I'm worried about my girlfriend. She is so sweet and kind and does not deserve this. What chance does she have of being pregnant?
