I would often talk about sexual fantasies to women. At clubs or bars, or any pickup scene for that matter, I would often try to tell them what I would "hypothetically" do to them if we were having sex.
Just last monday after our big test, we had a 3 hour "booze" cruise in which about 50 ppl jump on a boat with an open bar and drink until we drop dead. This is probably the best opportunity in the semester to pick up girls, so I stayed sober and kept working. I got really closed to this one girl, did some heavy kino, talked really really dirty with my hypothetical sexual situations, and eventually made out with her. The friday of that week she called me and actually asked me out, which led to our inevitable fvcking that night.
She said that she couldn't stop thinking about me after I said all those things that I was going to do to her that night. Ladies have a really good imagination, that's why most women read romantic novels to get themselves off. If you talk dirty to them there's no doubt that they would have YOU in their mind fvcking the hell out of them... which is just mentally practicing for the real thing.
