How long should I wait before we start stealing bases?

Girls and their games. It really annoys me. You wait until both of you want to do something. You won't seem like a slut because you only do things with mature partners that will keep your private interactions private.

Take your time. If you rush into things, then he will either think you're easy, or he could possibly be using you for sex. There isn't a magical timetable. But just remember that once you reach a stage, it's not long before you get bored and cross over into the next stage. So take your time, don't rush into anything. If you're getting physical early, how are you going to know if he really likes you, or just likes you for what you have and what you're giving up him?

Go at your own pace. If you know you are not a slut, then you are not one. I never believed that there was a specific time/place/date that anything has to be done in order for it to be appropriate, in a relationship that is. Don't rush yourself, but at the same time, don't hold back if you want it, he wants it, and there's nothing else holding you back. If you feel like messing around with him is the ONLY way you'll keep him, then drop him.
