ok so i am 31yr old man and am having a problems getting aroused, about a year ago one weekend i tried cocaine for the first time and both times i tried to have sex that weekend i could not get hard enough to preform, ever since then i have had problems getting aroused and im i happen to do get hard i have to concentrate extra hard and try to finish really quickly, this is becoming a big problem in my life and is effecting my self esteem, i dont know if i got some mental block from that weekend or what happened, i get a little exercise and am 6'1 150lbs, so i dont know if that has anything to do with it, also i stress alot and dont know how to deal with it so i dont know if that has anything to do with it and i also worry every time i get ready to have sex that i wont be able to preform also i seem to be able to arouse myself and finish just fine, any suggestions, advice, whatever i am willing to try and would appreciate.
