I have this problem and I was wondering if other people have also experienced this....
WARNING: X RATED
It's the opposite of premature ejaculation, which hear is quite common.
Try as I might... I can't ejaculate inside a girl... sex can go on for upwards of 30 minutes and the girl will cum 5 times... and nothing... I have to use my hands. I've had some pretty tight girls but nothing is right. I have to be doing it myself in order to get an orgasm. I suspect this is due to excess masturbation. Does anybody else have this problem? How can I fix it?
