Orgasming??!

Janie
Hi! So I've masturbated since I was 15, I am now almost 18. I orgasm quite often I believe, but during sex either me or my boyfriend has to rub down there for me to get to that point. I have never orgasmed from penis-in-vagina alone. Is that orgasm different from the one you experience when you masturbate? Also, why do I never squirt?
