Hi I am almost 20 and I have found that I do not get erections any more. Its been a couple months since I've had my own erection, the only times I get hard is with my girl friend and I've noticed that when I do its not as hard as I used to get. I'd say its mental but its been awhile and still nothing. Not sure if this helps but lately I've noticed that situations where i might get hard, i have more an urge to pee rather than actually getting hard. Is this something I should get checked out?
