It took me 2 years of having sex to find out how an orgasm feels like. It was always clitoral stimulation which, don't get me wrong, feels great, but is nothing like having him hit the G-spot until you orgasm.
My new boyfriend of 5 months is pretty good at reaching it everytime, but not making me climax. It takes a while, and I'm sure most women are like that.
Eiri, don't give up! You'll get there
