I am 24, started having sex with one partner only, at age 18 and have been with him since and I have only had ONE orgasm . I always feel like I'm at the point about to do it but then it just fades away. What is wrong with me??? My boyfriend doesn't know about this because I fake it everytime. Don't get me wrong it is great sex but I just can't get the full on orgasm. We have tried several positions, done it in different and unusual places and have just done oral but I still can not orgasm. The only medication I am on is synthroid for hypothryroid which is not suppose to have sexual side effect, so I don't know what it could be! ANY suggestions???? Please help!!!!
