Seperation of the species ! Again we see men and women are at times complete opposites.
Ask any married man of 15+ years what bothers him the most...Lack of sex. Not lack of "good" sex, just sex !
We've been married 24 years and sex is 2 times a month. And it's very good, especially for my wife. She has her over the top, eyes rolled back orgasm, and she is good for at least 2 weeks, if not more. Not Me, No Way !
We don't argue about it, but she knows that I get miserable as time goes on w/o sex. I get cold, unattentive, uinresponsive, etc. So to bring me around, she'll jerk me off every now and then.
I don't make a big thing about masturbation, she knows I do it, but I don't flaunt it either. Women don't need the stress relief that men do from sex, or ejaculation.
For women sex is a "happy place" they go to, play around for awhile and leave, not having to worry about coming back to visit any time soon.
For men, sex is a primal urge, that saps us of our strength and energy and leaves us wanting more. Just look at this site, it's about the PENIS ! Women don't have a Vagina Support Group site do they ?
I have also felt resentment, anger, rejection and unloved by my wifes lack of sexual desire. But that doesn't mean she's cheating on me. Our penises have been our little play toy since we were 4 years old, right? We grew up giving them all the attention they desired.
Now we find out that our partners (wives) never had their own "plaything" and really don't get the concept of the penis being more than just a tool for procreation. Where men feel it's more for recreation.
This is just the way it is.
