Hello I am 19 years young and my girlfriend and I grew up together then we started dating when she was 9 and I was 11 and we dated for 8 years the first 5 and a half of those years we barely saw each other at all we had basically a phone relationship then we broke up for a few months then got back together so it was off and on for a few months and with me not seeing her it was like a friend I never knew.lol then we broke up again for like a year then we got back together June 9 of 07 and we had sex on July 9 of 07 that was my first time but it wasn't hers and I was half drunk and so when I wasn't able to have an orgasm we thought it was that, and we tried twice after that and the last time was about 6 days ago and same thing, this long story is to say I know her but I don't know her so that could be the reason and she is the only girl that I ever really been with as in making out and sex and we just got that close not too long ago so I still get a bit jittery round her could this be my main issue of why I can have and orgasm when we have sex??
