Every woman is somewhat different so it is essential that each woman train her man on how to give her that ogasm. Unfortunately, women won't do this. Women say, "Here is my THANG, you figure out what to do with it. Of course men are clueless, leaving women frustrated. So I say it is women's fault for not getting their ogasms. Men are not mind readers.
My own wife is extremely fussy about the lubricant we use. It must be SYLK and none other. She simply cannot get it off without SYLK lube. Then she depends on my Magical Fingers to lightly rub & massage the vulva, and this takes a good 1/2 hour, but the results are amazing. Then she takes good care of me. She has NEVER had an ogasm from intercourse. Neither do most women according to Dr. Betty research. http://dodsonandross.com/
