....... I'm pretty low-maintenance.  A bottle of water is always nice.  Food?  No.  Candy?  No.  Smile?  Yes.  Hug?  Yes.  Kiss?  Yes.  You get the picture.  

I like it that you're asking the question, though.  Continually upgrading the brand, so to speak.  Very nice.

Gatorade and green grapes..

Seedless please

I always had individual sized personal items in a basket for the guys to use.  Soaps (bars and liquid), shampoos, lotions, combs, toothbrush and paste, etc.).  I don't like the idea of the big bottles of stuff....personal size is,  well, more personal.  LOL  and it is no big deal to loss anything that's left over.  Always afraid about germs being shared and spread with the big bottles.

Also, I offered bottled water and, sometimes, had fresh fruit, chocolate, home-made cookies.  If it's a special date, such as his birthday, I would have a small birthday cake and wine (fruit juice for the non-drinkers).

I turn off the lights and use candles instead.  If I remember to turn it on, I play music.  I've also thrown rose petals all over the bed and dressers.    

Some men appreciate the extra effort, others just want to fuck and don't care about AMBIANCE and all the extras.

I know its practically impossible if your incall is out of a hotel room, but for those with the technology available, have a selection of various types of porn.  (You can forget about the gay stuff).  I especially like the geezer-and-cheerleader-who-forgot-to-wear-panties type stuff, lol.
