That's essentially what this study is saying:
Makes perfect sense. Males evolved to take advantage of every sexual opportunity that presents to them. After all, unlike women, men could decide after conception whether to dedicate resources to nurturing their offspring (women were stuck being pregnant). When men do decide to commit and dedicate resources, the qualities that they seek are different.
If you are a woman interested in attracting quality men for long term commitment, it is probably helpful to still show some vulnerability (potential for easy sex) by acting receptive and playing a bit dumb. 100% prim and proper does not grab male attention. However, if you act 100% dumb, you will be treated as such.
