Women have strong biological incentives to have fewer partners, even with birth control - they are far more susceptible to sexually transmitted diseases, for one, as well as violence, and more partners means more risk of any one partner being a problem on that front. And all it takes is one.
If resources are constrained, it’s a toss up if it’s better to have one dedicated partner with a strong bond, or multiple partners with weaker bonds. Depends I imagine on a lot of other dynamics, and if there are kids involved.
There certainly are dynamics where many weaker bonded partners is worth the risk, or prostitution wouldn’t be the world’s oldest profession.
