I cannot remember the percentages, but a large proportion of women are, I believe, more easily stimulated orally than by pentration ...

The other thing is to try different positions ... it depends somewhat on the shape and fit of you to each other (if you know what I mean hehe).

Ummm not to get too graphic but one bf i got better sex from behind, another bf he actually hurt me cos he would bump against my cervix. For him it was better me on top.

Gentle experimentation and plenty of lube ... imo ...

good luck sweetie
