I wouldn't classify myself as an "expert," but I've had a lot of success getting women wet with nothing but words.
Just for the sheer hell of it (and btw, this stuff does NOT substitute for normal, healthy, physical interaction with women), I talked one "church girl" into sending me XXX pictures the night she "met" me. Another girl I met in the same room kept telling me I needed Jesus, but I played her HARD, and within a few mins, she was letting me listen on Yahoo messenger as she played with herself and said my name.
It was hilarious.
My point is that it can definitely be done... and MUCH more so if you are actually there with her and can use voice inflection and your eyes. Your eyes are what will REALLY impact her... much more so than your words.
If she has a high IL, it's pretty easy. If not, you'll have to work harder.
The main idea is to find her fantasy and play on it. Or, find her "bad side" and bring it out. This is especially effective on religious girls and your general "daddy's girl" types.
All women are pretty horny, some just have it buried pretty deeply because they don't want to be perceived as a slut.
You have to uncover her "inner goddess" and put her in a position where she wants to show you that she is not a "good girl" or a "prude."
I'm too lazy to keep typing. *lol* Maybe I can elaborate more later.
Again, the stuff I've done on the 'net, and getting girls wet online, I don't recommend that people sit around and do it all day or substitute it for real life interaction. I just did it for the hell and the fun of it.
