Mackw,

With all due respect, here's some advice. If you're going to be married soon and you don't want this to be a hurdle, please don't waste time on here talking to us about it. Go talk to her about why she is not satisfied. The basis of good sex is good communication. If you can't talk about it, you shouldn't be doing it. And if you can't talk about sex, you probably need to take a serious look at whether you are ready to be married.

Good luck!
