I'm about to turn 22 and I have never orgasmed. I have tried by myself with and without vibrators and during sex. When I masturbate I feel it start to come, try to let it, but all of a sudden pleasure turns to an oversensitive clitoris which I can't even touch anymore and a feeling of not wanting to continue. My boyfriend says I should push through it and it should be sensitive, but it's not a good feeling at all I don't want to continue I twitch and shudder at it. I don't know what to do, if this is in my mind I don't know how to control it. I feel like I'm always horny because I can't ever finish and it's very frustrating. Thanks :)
