I was talking to this girl for about a half an hour and we were hitting it off really well. And I just told her, "I already want to kiss you so bad right now but I can't." When she asked why I told her because I didn't want her to think that's all I wanted from her and that I was some player." Her response was basically to pin me down and make out with me lol

I find this works a lot, though. Like if I've really been having a good time with a girl and are getting ready to have sex I offer up some of my own LMR. I've told girls that I don't think it's a good idea to move too fast but I'm having serious issues resisting her (which is true and how I often feel). I find most women have similar problems, both with fear of moving too fast and inability to say no to me. So when I bring it up before they do it helps her know I'm kind of on the same page as her and she doesn't have to worry about me not texting tomorrow.

Note: You can't act too passive or weak doing this. It has to come from a place of power and confidence. It's more an admission that you're worried it may keep the two of you from hanging out more in the future than it is being afraid your friends will find out or whatever.
