Makes sense when you think about it. They know men would not prefer them (all else being equal), so they might just be more aggressive or suggestive than normal-weight women.

It means that, contrary to what one might expect, overweight and obese women are not having sex later, less frequently or with fewer partners than normal-weight women. There is a significant difference, however, on whether they have ever had sexual intercourse with men. Overweight (92.5%) and obese (91.5%) women are significantly more likely ever to have had sexual intercourse with men than normal-weight women (87.4%)
