Be a participant and try to have fun, don't just lay there asking for acrobatics and expect to have a fabulous time.  Maybe you will, likely you won't.  It does take two to tango.

Share your personality!  Be present.  Be kind.  Be funny.  Tell an interesting story.   What is it that makes you, you?  I'm not talking intimate or indiscreet details, but put a little of yourself into the time.  One of the fascinating things about being a provider is the variety of individuals that we meet, give us the gift of some of YOU.

I think the one little thing you can do is...

Keep your temper in check... She doesn't want to see that nasty green ass of yours..

Hygiene
Discrete and accurate donation
A token of affectio

Guys obviously don't moan and scream like women do, but make SOME noise!  A lot of guys are silent during sex, like ninjas.

Since 99% of the time I've done my research and am more than pleased or awe struck when the door opens I'll usually spew out some lame but cute sounding compliment. "Damn you're cuter than a speckled puppy" or just a juvenile sounding "daaaammnnn" with a shit eating grin let's her know that I'm obviously impressed with her looks. A little small talk and if ya can get her laughing you're golden. The saying if ya can make a lady laugh ya can make her do anything is pretty spot on.

I get that a lot of men never clean. I don't care if whatever room we're not in is trashed. (ie, living room, kitchen) but there are a few spots that should be sparkling.  
-BATHROOM is number one. Have hand soap, put the seat down, clean the toilet, have fresh towels just for me. Don't make me sniff around to find the least mildewy smelling one. Please have conditioner if you're inviting an overnight guest. It's like a $1 for cheap Suave brand.
-Fresh sheets are vital.  
-*Keep the dog out of the bedroom, especially when we're naked.* I love animals but I don't want to fight for bed space or breathing air and I don't want Fido to react badly if he thinks I'm hurting you.  
-If I'm staying a few days, please give me a place to unpack and stow stuff. Show me where a convenient plug is for my electronics. Warn me of what to say/do if someone you know stops by or notices us in public. I can usually roll with it, but it'll reduce the stress.
-Warn me when you take viagra, or at least when you take more than 25mg.  Don't try to hold out past 15/20 minutes of straight in-and-out pounding and/or fucking. If we go too long and I get sore, round two is not going to be as much fun.  
-Put the donation out someplace OBVIOUS, right at the beginning so I don't have to ask for it. It's really awkward having to break the magic with "Do you have an envelope for me?".
-This is personal to me, but I like unrefrigerated bottled water. (sensitive teeth.)  
-Don't do drugs before I get there. If you indulge, ask if it's okay. I won't join you, but if you're into 420 it's not going to bother me much. Anything else is a no. No, I cannot get you coke. No, I don't want some of yours. No, you can't pay me in it. Please don't smoke anything in the same room I'm going to be stuck in for the next 60 minutes.  
-If you smoke cigarettes, gum isn't going to hide it. Stop a few hours ahead of time and BRUSH. Like a million times. Seriously. Ew. For some reason the taste reminds me of an ex from college and I have an automatic recoil.(He was a dick.)
-Have AA batteries on hand, just in case. ;]
-Massages! Massages? MASSAGES! They go both ways. Like me!

Just RELAX.....

Just do it!!! ........

and that means LISTEN TO HER!
