I get that way. I'm an incall provider but the night before, if it's someone I haven't met I get giddy to meet a new gent and if it's a returning friend and we have a little escapade planned with my we-vibe or something (wink), then I'm even more giddy!
That night I usually can't get it out of my head until I "do something about it while replaying it" and then I can usually go right to sleep

Does anyone else lose sleep the night before a session…or the night afterwards? I do.
The night before, if I’ve never met the lady, I’m reviewing directions to her place in my mind (if she’s given me her address already), where to park (I’ve usually checked Google Maps to scope out the area), where I’m going to leave the wallet, phone, etc. I’m reminding myself not to forget the envelope. I’m thinking about making sure I don't get any traffic tickets in an area where I normally would have no reason to be in (hard to explain to the SO).
If I’ve met the lady, it’s more like anticipating all the great fun we’re going to have again!
The night afterwards, the tape of our session keeps replaying itself over and over again, a real delight.
So, it’s a good thing I only have a limited hobby budget, or I’d never get any sleep! Maybe it gets less this way for long-timers…but, for me, after less than a year in the hobby, it’s like this most of the time.
Am I the only one?
