This thread produced a lot of discussion about when women should first have sex with a man if they desire a relationship with him. Many women in the thread argued that a man will lose interest in a relationship if they have sex too soon, especially on the first date. That claim seems absurd to me; in my experience, men only pump and dump low-value women.

Put yourself in the shoes of a man. There's a woman who's attractive, fun, and sexually interested in you. If she's attractive, why wouldn't you want to have sex with her? If she's attractive and fun, why wouldn't you want to have sex with her repeatedly? If she's attractive and fun, and you know she's willing to have sex with you, what man is going to turn that down? It's laughable to think there are tons of men out there blowing off attractive, fun, sexually interested women simply because "but she had sex with me too soon!!" Every man is going to call that type of woman back.

The women who get pumped and dumped, then, are either not attractive, not fun, or not sexually interested (i.e. they had vanilla, emotionless, starfish sex). Men will still have sex with these women (it takes a lot for men to turn down sex), but they aren't going to put much effort into repeating the experience because she wasn't all that great. The good news here is that this gives women who are tired of getting pumped and dumped an internal goal to focus on -- if they become attractive enough, if they become fun enough, and if they express their sexual interest strongly enough men will call them back. It's not him; it's you.
