I would suggest stimulating your own clitoris will having intercourse. Sometimes we girls just have to help ourselves.
I am the same way...there is nothing wrong with you...at least I dont think so..
Typically stimulation of your clitoris is what will give you an orgasm...and during sex there USually isnt much coming in contact with your clitoris, or at least in my case...So correct me if im wrong but thats the only reason i, personally, dont orgasm during sex, but do when i am recieving oral sex.
