Attention: If you feel comfortable discussing such things with the dr., tell them of your distress. Bringing it to light may have it lessen or go away altogether under those circumstances. Yes, it is normal for some people, both men and women, of your age to experience this. It is part of the sexual instinct, but can be alarming in a clinical setting.
