For the past couple years, I've had problems ejacuating... there are times it get's semi hard and I can have sex until I'm worn out and have to stop, BUT, I can not ejacuate. When this happens, it upsets my G/F because she thinks it is her fault I can't cum. Sometimes I fake an Orgasm (hey, you girls can do it sometimes, why not?).. I can't cum even with oral sex or by masturbation. What the hell causes this?? Then there are times that no matter what... it will not get hard... now my G/F is a wonderful lover.. none better. I usually get her off by doing the G-spot and clit at the same time with my fingers and by oral sex. The only good thing about not getting hard is that I have prefected the Oral sex and working on the G-spot and Clit. If anyone has any ideas or can give any suggestions, PLEASE HELP ME.!
