Dear Diana,
I am 25 and have a girlfriend. We have been having a physical relationship, but ever since I have started going to the gym, I haven't been able to be as intimate with her as before. Is it a side effect of working out? My friends think that this change has a lot to do with my bulging muscles.

Dear Umesh,
You need medical advice, consult a sexologist to clear your doubts. In general, a higher testosterone level in males increases the sex drive. When a man's testosterone level begins to fall as he ages or due to other factors, the libido starts to diminish as well. May be you are overdoing at the gym and the exercises are affecting your sex drive. Instead of listening to your friends, check with your trainer as well.
