Oh those are good ones, JSmooth!
I actually used one similar to the "Hot Guy = Bad Sex OR Ugly Guy - Great Sex" last night and it worked really well. Either answer is an excellent neg op. I almost got thrown off when she asked which one I was, but I took it as a shit test and just replied, "wow, I've only been here two minutes and you're already wanting to know how I am in bed. You need to slow down honey. At least take me out to dinner first.

"
I didn't use it as an opener last night, but threaded it into the convo which almost worked better. As I suspected, it turned into a little game for a few minutes, then I switched threads and continued the convo. As it is right now, it seems a little too brazen for an opener. I mean, who would really ask that right out of the hole? I need to refine it a little bit to get it to work well as an opener.
Right now though, it seems to be pretty good at lowering defenses, especially if you are negging occasionally.
