I had this happen briefly. I had been on T for about 2.5 months. I don't know if this is what caused the sensitivity or not, but I decided to take some resveratrol. I'm thinking that maybe the combination of the resveratrol and the T caused the problem, but I really don't know for sure. I quit taking the resveratrol and then the sensitivity went away. It only lasted about one week, but for that one week it was pretty bad. In general, I haven't heard many people say they've had this problem on T.
