Outside the meet:
PM's. Not "When do you want to see me" PM's. The "conversational" kind that can extend over days or weeks (thus violating the "you're wasting my time" rule). Sometimes replies are rapid fire - sometimes don't come for days (we all have lives and jobs, right?) When this happens (as it did with Brooke recently) it really impresses me. I don't care if the bottom line from the lady is "maybe this'll get him to see me" as long as it doesn't come across that way. Even if the conversation drops off to nothing, I remember.
Texts - not for everyone, but anyone that has my number can text me anytime. Some have and it's damned nice to get a "Hey! Thinking about you!" sometimes.
PM's - not to be confused with the "conversational" - this is the "Had a great time", or "Thanks for the review" PM's after a meet. Let's me know I wasn't forgotten after I left. Again - I don't care if the intent is "come see me again" as long as it doesn't make me feel that way (see you 3 times and get "Had a great time! Come see me again!" messages all three times and I'm likely to think this is a canned response...)
At the meet:
Not rushing.
Smiling - make me feel like you're enjoying the time as much as I am.
Be willing to "go with the flow" - Some women have a "routine" worked out that pretty much ensures a delightful (hoping here that "delightful" isn't some sort of trademark already
) visit. Don't try to get back on track if I cause a detour. I noticed my favorite has a "path to victory" which - quite frankly - I can't argue with. But sometimes I'd rather give more than receive or just alter "the norm". Sometimes she tries something new. It keeps it exciting. On the flip side, I saw a different woman who - when I tried to go left HARD steered me back right. She had her routine and she was sticking to it.
Guess those would be mine. I agree with domeindfdub so far on the rest.
