1. Connection and being in synch with sexual activities. Personally, I don't care what a gal is into for her personal interests like music, movies, etc. What matters most is a high energy sex drive on her part. She has to be into the sex as much as I am. The ultimate goal is for both to provide pleasure for each other during the encounter. If the pleasure is just one way, it seems mechanical and trite.
2. A girl who can go with the flow instead of some pre-scripted set of routine activities. To me, this means a gal who's menu is pretty accommodating from the get-go in order to allow for spontaneity and creativity while having fun. It's no fun to about to go down on a lady only to hear that is not on the menu. So for me, a gal needs to be BBBJ, DATY, MSOG, MPCFS and open to Greek (although the latter is not a necessity).
3. Physically attractive. There have been a couple of times when I've met a lady and have been disappointed by her looks. Yeah, I know that is shallow and vain, but that is why I pay

This also relates to hygiene as well. There have been a couple of times when I've wanted to go down on a lady but didn't due to a "not-so fresh" smell coming from the honey pot. That will probably stop me from repeating with a lady.
