I am 24 and perfectly healthy, and very attractive to most. I have not been able to ejaculate from oral sex or by 'jacking off'. It has become a problem recently because I am now involved in a relationship. My partner is turned off by the fact that I can only cum during 'frottage', or rubbing up against each other, usually with lubricant. I have come very close to cumming while receiving oral or while I have given myself hand jobs, but something about me just can't relax enough to let it go. I grew up masturbating by rubbing against pillows and blankets. Maybe my sensitivity is gone? Or maybe it is just mental. I would really like help with this. It would be so nice to relax and get off without all the effort that frottage takes. Intercourse isn't an option at this time, and may never be as my inability thus far to get off by other means has put a huge damper between my partner and I. When I have had intercourse before, I can get off fine.
