It's all a matter of frame--and frame starts with how you frame a given interaction/result to yourself. I see rejection as amusing--I mean obviously the girl wants me but doesn't have to confidence to think she can hold me down; or she's just shy; or she is afraid of seeming slutty (OK, so you see how that statement isn't necessarily true but it's a much more useful frame than hanging your self worth in the balance every time you make a move on a girl). Plates also help.
I actually have a recent anecdote that touches on this subject. Two weekends ago, I met a girl at my buddy's house--friend of his gf, lives out of town. She was hot but super reserved (wouldn't even make eye contact). We all go to bed--and she and I are on couches in the living room (she lies down first and pretends to go to sleep). I start talking to her and invite her over to my couch (which was like 3x the size of the one she was on). She declines. We talk--I keep trying to sexualize the conversation; she laughs but doesn't bite. She is making eye contact though. So I grab her arm, start stroking her forearm, look her in the eye, and tell her to come over to my couch. She declines. We go to sleep.
At this point, I've been 'rejected' for a solid 4 or 5 hours (the entire time I've known this girl). She tells my boy and his gf about how I tried to get her to share my couch the next morning. But since my self worth still isn't affected I can share some laughs with them about it--they know how I am. Plus, my frame is still that this girl really wants to sleep with me.
So fast forward to 4 or 5 days ago--I'm in a city that's closer to where this girl lives (on unrelated business). I look her up on FB and shoot her some messages, joking that we should hang out again but she's a little too sexually aggressive and'll have to tone it down. Busting on her for being shy. She starts to qualify. I ask her how far away she is from the city I'm in--she answers; I tell her I can possibly make a detour for Saturday night. Long story short, I get there and we go 4x over the course of the night.
I had plenty of opportunities to let her 'reject' me. But I had a frame that allowed me to call her bluff and make things happen in the total absence of positive reinforcement.
