>>11067238It's basically indoctrination via ignorance from experience. Females who find themselves in "virgin" bride territory are usually dissuaded or isolated from situations that lead to multiple sex partners. This is because of either religious reasons, heavy social pressures and/or high economic value of a untouched young wife. If a female is allowed to experience sexual relationships on her own terms she will usually explore multiple men. Mostly because non-committal relationships are fickle with nothing depending on the outcome. But also because our biology isn't exclusively interested in commitment. Obviously this will lead to her being devalued by men looking for marriage (not necessarily sex) and society to varied extent.
There's also the fact that some of the women could be lying in such studies. A virgin bride could have one partner on "record", maintain a "stable" marriage but have a lover on the side (which has been recorded in history multiple times) be it male or female.
Personally I don't trust such graphs too much. It's way to easy for someone to lie about sex partners even assuming they are in a stable marriage.
