Random thing that I tried that worked really well for me in the past. I did this RIGHT after I started learning the DJ ways:
I was talking to a girl I'd just met a few days before. She brought up sex stuff and asked stuff like, "what's your favorite position, do you like giving oral?" after having gone through a laundry list of **** she's into.
Normally I would've just launched into it and had the conversation, but on that day I had an idea. I said, "Oh, I don't really like talking about that kind of stuff with someone I don't know too well. It seems kind of tasteless to me."
She was floored. I guess partially because, since she was a nine, most guys are MORE than willing to talk about sex with her all day long. She was also kind of embarassed because I'd essentially negged her and called her a slut.
She ended up being, by far, the hottest girl I've ever had fall in love with me.
So maybe you could try that one out one day.
