i'm 17 currently having a problem maintaining a erection, I cannot think and get one like i use to like last year.. neither from watching porn.. is it because im thinking negative too much? and should i be taking viagra because i bought it today he said take half of the pill.. will i also be able to overcome this once it works and everything will be fine as it use to be.. ill let u be the judge on that

have u got any suggestions on how to fix it rather then viagra mate, i didnt think so..
