Hi I'm a 16 almost 17 year old boy. I have tried many times to masturbate but every time I try nothing happens and I eventually go limp. I will go for a half hour to maybe even an hour sometimes depending on when I get tired. I first had sex when I was 14 and I never really masturbated before that with any success. I have ejaculated many times during sex so I know I'm mature enough but still for some reason I can not ejaculate without a partner. Since me and my girlfriend broke up I have had the need for sexual release but have not been able to do it on my own. Any suggestions?
I think it would help to have visual stimulation. Look in fashon magazines or guy magazines, like maxim and playboy.
I am not a doctor, but hope this helps:)
