Just wanted to post my go to line that I use before turning the conversation sexual. I've field tested it a plethora of times in both day and night game, and at this point in pretty much 98% of my sets for the last year. And it works every time.

There's really only two guidelines to using this line: the first time you think of something sexual about her drop the line, and pause for dramatic effect after "Look".

Right after the line, I'll say something like "that dress makes your ass look amazing."

This isn't some secret escalation technique, just to be used to turn the conversation sexual. The girl doesn't matter, but the timing does; build a little rapport before as well.
