last year i noticed that i was developing a weaker erection. im 21 so my erections were pretty much rock solid but i started noticed them getting weaker but still strong enough to penetrate so i didnt really pay no mind. then i started noticed my production of pre-cum has went through the roof. now im having these wierd headaches everytime i get an erection. has anyone ever heard of this im starting to become impotent. im planning to see a doctor next week but ive been search the web and i cant find anything. any input or feedback will be appreciate thanks.
