Based on all I've read and on what my wife has told me, I'm of the opinion that many wives have never, and will never orgasm with their husband in their vagina. Women are very, very good at faking orgasm and we males are anxious to buy off on it. Oddly, my wife cums quickly with any man lucky enough to penetrate her anus and hold off cumming for a few minutes. She'll have multiple orgasms this way and it's just beautiful/erotic to watch, even when she's under the covers with him. We've talked about it numerous times and both of us are of the opinion that her desire not to get PG with her first husband is how she came to be the way she is. Anal sex might be the best contraceptive! A few years into our marriage, she finally began having orgasms with her BF in her vagina, but still has not had one with me that way. Or so she says.... We've discussed all of this in a very matter-of-fact way although there's an aspect of humilitation that can't be denied. I quickly learned how to please her anally, when to do it, etc. She's been remarkably consistent: She likes it prone or missionary.
