I want to LIVE.

I’m 21 years old and I have the best boyfriend ever ( we’ve been together for three months now) I had many boyfriends before, but I never slept with any of them( cultural reasons) but this guy is a foreigner (he is from Australia) and we started to have sex, he taught me many things and he is very gentle and I think i can please him during sex very well, because that’s exactly what he tells me, but the PROBLEM ISSS!! I don’t know how to rub my vagina in the right way during masturbation and I don’t know how to cum. Therefore, when he licks my vagina i pretend like I feel good and cum but I don’t, i don’t know how to masturbate in the right way, I used to rub my vagina with pillow and i never saw how it’s being rubbed so I don’t really know how to do that, i really want solutions that do not include him teaching me how to rub my vagina... thanks.
