take to prevent such conditions? My girlfriend and I have sex roughly 5-7 times per day, almost everyday. We have been doing this for about about two weeks. Before the two weeks, we had sex roughly about 1-3 times per day for several months. Lately, I have been getting exhausted and my penis seems to feel numb at times. What measures can I take to keep my penis healthy and labido high? Are there any health conditions I should be worried about?
