Been married for a year now and I love my wife and we have some great sex. I can get her off very easy by fingering her clit. I mean she REALLY seems to get off on clit fingering, most of the time about an hour of rolling around taking turns on pleasuring each other I can get her off and she cums big time, I am talking like squirting a little to A LOT and I mean a lot of fluid that can shoot from 6 inches to 3 feet. She generally only orgasm once this way and she cant move for about 5 minutes after and I cant touch the clit much if any at all for the night at that.
She likes oral but I have never been able to really excite her with it and never made her orgasm with it. I have also never been able to get her g-spot or at least get a reaction that shows me I am at the g-spot. I know the g-spot is a different feeling the clit stimulation from what I read anyway so is it possible she just never had g-spot stimulation before and not use to it or am I just doing something wrong. She does seem to get excited when we actually have intercourse and I seem to hit spots in her which cause greater excitement anyway.
I really really want to get her into one of those multiple orgasm modes where I can give her many orgasms in a single session but I just cant seem to figure it out.


OK, that is what you want. What does she want? About a quarter of all women never reach orgasm. Probably about ten percent have ever had their G-Spot located and stimulated to orgasm. Many women are perfectly well satisfied with one orgasm - we can be satisfied without being satiated. Most women, following a crashing orgasm as you describe, simply want to cuddle and come down from the heights.
Get real. Aim to satisfy her, not you, with her response.
