The last few girls that I've been with, I've found that when we've been intimate, the next time we hangout, they don't put out. But every time after this, they do. Why? Jon B.
How long are you waiting to be intimate? It sounds like you're rushing into it and the girl regrets it afterwards. She's giving you a non verbal message that she wants more than sex with you, by not "putting out" the next time. She's testing you to see how you'll respond – whether you'll be upset or accept it. She wants you to know she has more to offer than her body.
