I stumbled across this article 'The Science of Cuckoldry' and found it quite insightful.

Some highlights:

A woman has a dual sex drive.

uh-huh

The first is centered on finding a mate for life to help support her and her offspring.

Really?

This is why (and when) love is such an important part of a women’s sexual desire.

So that's what love is, being a mate for life to provide for her and her offspring. Please continue:

The second is a desire to obtain a variety of the best genetic material to produce the best children. This second desire begins to grow once a woman has found her life mate and grows stronger as time with him progresses. Eventually, this later and more powerful drive overpowers her sexual desire for her life mate.

Fascinating. Someone should really make a subreddit discussing this stuff.

While all evidence indicates that a married woman both physiologically and psychologically does need a variety of sexual partners, a married man does not.

Of course he doesn't! Who would think such a thing?

Husbands in clinical studies who’s desire for their wives have waned and who’s interest have turned to other women have been completely turned around when their wives begin using arousal and denial techniques on them. These techniques instill uncertainty in the husband as to whether he will be allowed to complete a sex act with her or not. Time after time, in study after study, these husband’s desires have been focused back to their wives exclusively, losing all interest in other women.

What? What? What? You're not seriously suggesting that women use manipulative techniques to keep their husband's interested are you?

I wanted to find out more about the arousal and denial techniques to make sure they were ethical, which lead me to this article

Emily is just one of a growing number of women who practice erotic sexual denial, also known as orgasm denial or orgasm control, a sexual practice in which a man is kept in a heightened state of sexual arousal for an extended length of time without orgasm. The length of time can range from hours and days to weeks and months.

“He’s much more attentive to me when he hasn’t cum for a while, much more willing to please me, to communicate with me.” says Emily. “He sees an orgasm as a reward for making me happy and I can extend that for days, even weeks.”

Do you want to be a sex goddess – treated like a queen – wave your magic wand and get what you want? Of course you do, and you deserve to have it. Oh, the fun doesn’t stop there – not at all. By practicing male orgasm denial, you will be powerful – pleasured – pampered. Your sex partner will place you on a throne and aim to please you in every way possible.

Hmmm ...

Make no mistake about it – Emily is in control – her lover enjoys the results of being dominated by a woman who has mastered this art.

Well, I guess if he enjoys it ...

“My husband has become my willing slave, LOL.”

Oh thank God! For a minute there I thought the man might be in an abusive relationship, but clearly he's a willing slave. And that LOL is reassuring.

Kimberly says, “Tease and denial is a very important aspect. I’m really into edging and brewing guys. I also like to use some emotional teasing – like when I’m cumming, I’ll say something like, ‘Don’t you wish you could cum? But you’re just not worthy.’ I’ve also told him in the past a man’s orgasm is for making babies, and since we’re not trying to make a baby, why does he need to cum? I’ve also reasoned with him that a woman’s orgasm is purely for pleasure. I guess this some kind of mild brainwashing? LOL.”

Ah, so it's only mild brainwashing? That's OK then. Once again the LOL is reassuring.
