So, I have been practicing bringing up somewhat sexual comments on the first date. One kind of line I like to use is to ask a girl if she works out and if she says yes say something along the lines of "wow you must have a great butt" after about 30 minutes into the date and hold my frame with whatever the girl says. On the past 3/4 dates the girls had relatively good responses but on this last one this sorority girl (more unattractive than the others) really kind of just turned off and by the end of the date all the attraction I had to this girl just died as she got pretty boring thereafter.

I am just curious as to if this is a solid way to bring up something sexual or if I should smooth it out. Also, what are some ways you guys bring this stuff up?
