I wonder if she can rebuild a carbeurator on a small block Chevy.
Seriously,
01) I look at her skin, imagine what it feels like against me, imagine the warmth and softness of it. I look at the muscle tone in her arms, her back, look at her posture, it says alot about her self respect and, consequently her enjoyability as a sexual partner. I look at her tits, how perky are they, how would they look laying down with nothing on. I look at her legs, her calves, her thighs. Is she fit and active? I gaze upon her crotch and absolutely, I wonder what it looks like under there. At this point I usually have to supress the growing urge.
02) I look at her body language, her smile, her laugh. I look at her eyes, is there life and happiness in there? I listen to her talk, is she self assured? this always leads to a much better time in the sack than the alternative. Does she allow other people and their ideas, their jokes, their opinions, to bounce around in her world, or does she reject them, unable or unwilling to open herself up to them. This is a VERY strong indicator of how adventurous and comfortable she is. By now I usually have a very good idea of how fun she would be in the sack.
03) Hell yeah, I wonder if she's the type that'll let you put it anywhere, I wonder if she's a maniac, basically.
