GG i think they r both neccesary , oral and fuck , coz all nerves and spots need to be stimulated for a full orgasm .There r planty of em located inside vagina made to be hit cant ignore em.
A girl told me, and i think she's right , that orgasm from oral is not enough for her to be completely satisfyed and she need fuck orgasm too.
I could say the same for me , cuming from BJ is awsome , very srtong feeling but i need to fuck her too , as i anwered in that " could bj b considered as sex ?" thread.
So we need the full package for 100% satisfaction guaranteed .
