Is it simply a tool they use to lock up betas? But if it was, they wouldn't exhibit this behavior towards alpha males/high status males. I have a few friends who fit the the stereotypical TRP alpha male archetype, and they've told me stories of girls who've acted prude and innocent only to have sex the first night, or even initiate the sex.

So what's the point of women acting like this? Is it part of their mating strategy?
