I'm not saying anything judgy about promiscuity. I've slept with people on a first date and not regretted it. BUT we are trying to get G to do something different as her old way of being is not working for her. And many women get too attached once that oxytocin from sex kicks in, and then end up not seeing all the red flags they should be seeing. She needs to learn to let a guy work to woo her, not be so easy. It helps to weed out the guys who are just looking for a convenient lay. Because unfortunately many guys will date a willing woman even if she's not the one for him, as a convenience for sex until the right one comes along. G has had too many experiences like that. And most men, for whatever its worth, seem to value the women they have to work hard to get, more than the ones who make it too easy for them. Waiting a couple more dates before having sex gives her time to find out more about him, if he's worthy, if he's hiding anything, if he's interested enough to keep pursuing her.
