You reach orgasm in a normal way. Women generally do not have an orgasm during intercourse, but through the stimulation of the clitoris. You have all the reasons to be happy with your sex life. Why not just enjoy it instead of trying to reach impossible goals? Men watching pornographic movies, where the actresses have multiple orgasms, believe that women also can have them in reality, but it is very unusual. These actresses are acting very well-- they are faking it, - and the films do not represent how it works in real life.
