Musashi:
Difficult to explain, but there was a study a while back that seemed to say that they can't really feel as much through the vagina itself.
Different experiences for different women. However, I was more confused over you saying that there are other pleasures besides oral sex but then saying that some don't seem to receive pleasure from the vagina.
