Doctor, I am a 19-year-old guy, and good at sport. Recently, I have been having little pains in my chest, near my heart. Could these be heart attacks?

Heart attacks are almost unknown in men as young as you - except if they have been messing with cocaine. However, I have seen vast numbers of young sportsmen who complained of pains in the chest, but whose problems turned out to be purely muscular. But for your own reassurance, have a doctor check you over.

I have to take two birth control pills a day in order to control my menses. Could this affect me negatively?

Occasionally, it is necessary to take two pills for the day, particularly if the person is very big. But I hope you are doing this under a doctor's supervision. Taking two per day does increase the risk of 'pill side effects.' But as you are young and (I hope) do not smoke, the danger of serious side effects, like clots, is not great.

I am a 20-year-old guy who is sexually active, and when I am having intercourse, I discharge very quick. Would thinking of other things help?

Yes, it would help a little bit. You could also ask a doctor to prescribe for you one of the antidepressant drugs which delay climax. Also, I suggest you use the Internet to look up the Masters-Johnson treatment of premature ejaculation.

I have been with my boyfriend for three years, and we have been having some problems, recently. The thing is, he thinks I am cheating on him! Is there any medical way I can prove to him that he is the only sexual partner I have?

No, I am afraid that there is no such medical test. Unfortunately, some young men are extraordinarily and irrationally jealous.

I should warn you that sometimes this jealousy arises at a point where the male's mind is subconsciously beginning to turn toward the idea of finding a reason to end the relationship. However, this may not necessarily be the case with your guy.

I am a guy of 17, and I love a girl of 13. I love her more than the life that God has given me. She loves me too. Everyone says she is too young for me, but intellectually, we are perfectly matched. Is loving her wrong, Doctor? Should I stop loving her?

This girl is too young for sex. But if your relationship is a mental and spiritual one, then I see no reason why your loving relationship should not continue. I wish you both well.
