I have a couple of routines that I use to turn the conversation sexual or towards their body. Yes, don't ask about measurements, that is just too obvious.
One routine I have right now is asking them if they are going anywhere for the summer. Or if they are going to spend some time on the beach. A lot of European girls spend a couple of weeks on the beach in summer. Then of course i say. But, the real question is "DO you look good in a bikini?" If she says "yes" you can ask her what she likes about her body. A lot of times they say they has a nice butt. Take the conversation from there. I flirt about coming to the beach with some suntan lotion and helping them out. Just so they don't get burnt. Cos that is the kind of considerate guy I am.
Another routine I use, if I haven't seen their picture, or sometimes even if I have is where I ask them questions like "How tall are you?", "What colour is your hair" "What colour are your eyes".. these are set up for my next question which is "Do you have a favourite perfume". They give me some name..whatever.. Then i pretend to go about behind them and smell the back of their neck to check out their perfume.. Which is a set up for my next comment.. which is "Did you feel my warm breath against your skin".. Now some of this might sound corny.. but the chicks love it. Trust me.
Also, you can turn up the sexual quotient by asking if they are adventurous. They usually like to say "yes" and then i ask them what adventurous things they have done. They usually tell me something boring. I then respond with a real erotic story that I have and tell them in detail, again being erotic, not explicit (there is a difference).
I have 3 girls right now I met a combination of these routines that just want to talk to me about sex every time i am online.
