Below are comments on the question: Are women naturally, or culturally, monogamous? They’re edited for brevity and clarity. I’ve organized them and added my comments in italics.

Polygamous women

• I seem to be different than the study, but then so are most males I know.
• Divorced at age 33, I experienced a natural heightening of sexual interest and there were a number of men with whom I had sex during the next 7-8 years. I enjoyed it all tremendously and learned at lot about men and about myself. During that time, I met only one man I would have considered as a life partner. Now I realize that the relationship was great because the sex was great.
• If women were paid equally and had equal opportunity in the job market, I think that monogamy would be weakened.  When I earned more my husband, and could survive financially on my own, my sexual behavior changed as well.

Polygamous men

• Sex is so pleasurable. Why limit yourself from pleasure so long as everyone knows the ground rules – that this is about pleasure and not about commitment or love.
• Sex is magical. I would like to have sex with as many women as possible. But I always thought women experienced sex the same as I do.  It hadn’t occurred to me that they might not.

Research suggests that women, on average, don’t enjoy sex as much as men do. U.S. women enjoy sex less than women in some cultures, but more than women in others. I’ll explore why later.

Jealousy and not loving equally

Women who are interested in polygamous sex can discover difficulties:

• As a lesbian I have a perspective that is completely woman oriented.  I personally have had more than one lover at a time and found it difficult since I was always trying to explain why I was leaving to visit someone else.  One always seems to love one more than the other.

Meeting social expectations: Women

• Here is my confession – two or three times I allowed myself to be picked up at a party or a bar. I am still so ashamed of those incidents. Remembering them makes me feel so dirty! I thought it was expected.  You know – times were changing.  Everybody did it. I now believe I let myself be used by men who were only after a little fun and had no serious intentions.
• I let myself be used by men who were only looking for fun… then I felt ashamed! Many women were brainwashed into believing they would enjoy it as much as men only to realize they were no more than a toilet bowl or conquest.  I am sorry to disappoint but sex ain’t all it’s cracked up to be. Many may hide the shame and humiliation they feel by saying they liked it.

Women are punished for sex
Some women feel pressured to have sex, but they are also punished when they have it, labeled “sluts”:

• The stigma attached to women likely keeps the number (of lovers they report) low
• (At least men) seem to have each others’ backs. Women don’t. They’re often quick to stab each other in the back.

Meeting social expectations: Men

• Men might be lying too since the cultural expectation for them seems to be quantity rather than quality.
• Men also have cultural expectations to live up to: amass notches on their belts.

Agreed. Women claim 5 lovers and men claim 12. Women must be underestimating and men exaggerating. The real number for both is likely in between: 8 or 9.

A man’s view:

• I wanted to have threesomes for the longest time. Then I realized it was largely about feeling left out of something I thought everyone else was doing.

There’s also plenty of research on how men feel pressured to notch up “conquests” in order to be valued by other men.

Shallow, one-dimensional vs deep, connected relationship

• Women prefer depth, romance, quality in a relationship. They know that the closer one is in spirituality, emotions, the better the sex. Women need that depth to be fulfilled.
• A purely physical relationship requires little work. You don’t have to concern yourself with messy thoughts or feelings beyond the immediate moment. It’s shallow and one dimensional. Real relationship takes depth: looking at someone’s worth beyond pretty eyes, nice butt, and teeth.
• I have heard some women say they enjoy casual sex – but in 62 years I have heard far more say they haven’t enjoyed any sex let alone casual – meaningless sex. It’s intimacy we want!  But I am still waiting for the rush of women who can honestly tell us about all the hot meaningless sex we have been missing! I’m all ears?

Men desiring depth, connection too:

A woman’s perspective

• I met both kinds of guys when I was dating. I met guys who seemed downright anxious to connect on a deeper level and guys who would lie in a NY minute if they thought it would get them into my pants faster.

A man’s perspective

• Our sexuality and the expression of it before and during (and after) marriage is, I am convinced, one of the more complicated aspects of what it means to be human. One could argue that God created men and women different sexually (in all the ways!) because to come together in meaningful intimacy (erotic or sexual) requires the development and expression of our deepest and highest virtues—sacrifice, humility, and kindness (even long-suffering at times!), and especially love. It is among the most meaningful and challenging dances we do.

And, don’t forget the men in men’s studies.  Both Michael Kimmel and John Stoltenberg recommend men do sex from a place of love and commitment, and they say that is where the come from, themselves.
