I can't orgasm during sex!

Kyleigh
I have never been able to orgasm during sex, the only way for me to orgasm is if I rub myself, use a vibrator or get eaten out for a long time and just the right way. It's starting to bother me because I'm in a serious relationship now but I don't know how to tell him that I want to use a vibrator or that I can't orgasm when we have sex. Help please ladies!
