I can relate from a man point of view in tasting my wife. I love to do it, and while any position is fine, being on my knees if just the best for me. Yes it is supposed to be the most submissive of positions and maybe it is, but to taste her delights, once, twice, three times...whatever it takes, I do.
She has been with 4 other guys, and they were terrible in bed. They would start to taste her, because that is what a couple is supposed to do I guess, but lapped her like a dog, and even then was only half-into it. The latter was really the problem, they only cared about what they were going to get, not about her needs. Me, I am the opposite, I love it, and I love her and want to show her that at this moment in time, it is about her needs, not mine.
The first time I ever got on my knees and tasted her, she recovered from her orgasm and said it was the first orgasm she ever had with a guy. I thought she was lying and flattering me, but that was not the case at all. A lot of guys out there are really that self-centered. Not me, I'll get my turn, so being on my knees tasting her delights...yum, yum, yum!
