Just fuck her.
That's pretty much it but I'll add in a story because we humans love stories. I have a lot of stories with this same moral.
I went on a date and killed it. She was rubbing her boobs on me for the last hour of the date, we were walking around looking at art. I generally make moves at the last moment, besides touching/massaging.
We get back to the cars and she asks for a hug and kisses my neck before I even am able to make my move. I then initiate making out and then move us into my car.
She just found out days ago that her BF of 3yrs was cheating on her. I felt bad for her. She was kind of neurotic and babbling and apologizing constantly over stupid shit.
So I trade in the mystery and coolness I built up over the date for niceness and I do something that is not my responsibility. I try to make her feel better. I decide "Oh, I don't want to fuck her head up by boning her so I'm just gonna stroke her tits and grab her ass and make out and lay her out over the center console while she gasps."
What would have made her feel better is fucking her. In retrospect she even made one of those ambiguous girl hints about coming over. "Oh, so you live really close to me?" x2
I didn't even try, I talked about hanging again soon. Now she doesn't even want to hang. I wasted my opportunity by worrying about something that is not my responsibility.
I have many similar stories where I rationalize not making a move. It's a miracle I'm not a virgin. I've literally been massaging a super hot girls thighs when they were stovetop hot and backed off. (she had a bf[not my responsibility!])
Anyways here's where you guys shit all over me but just remember, don't decide for the chick if she wants to get laid. You're all over her body, she probably wants to get laid dude, push a little further. She'll stop you if she wants to stop. Also, when she gives you the opportunity to fuck and you don't fuck her she gets bitter usually.
