In the winter time, or just walking out of the shower into a cold room, it's the opposite: "Please, no shrinkage. Comeon little turtle, out our your shell, there's nothing to fear".
Generally though, you run through the checklist again (the first time is before even heading out):
- do i have enough money: check
- fresh breath: check
- washed the scrotum and anus: check
Then, if it's a new girl you wonder what the possibilities are. If it's a regular you think about what's new to tell her or just think about what you're going to do after the session (back to work, dinner, etc.). There's always a bit of nervous energy but less so with a regular.
I liked the old IT that had magazines in the room to keep your mind occupied. My recommendation to the higher end spas that could afford it would be to put in some small flat screen TVs and let the guy flip between sports, stocks, news, etc. to pass the time. Then let the attendant turn it off or to whatever she wants when she enters the room. A 5 minute wait is nothing but 15-20 minutes and we need something to keep us occupied.
