As long as she's fresh for the booking and you can't see that she's just been ragged, visiting a prostitute is it not the expectation that she sees multiple punters the same day as you?
You quoted only half my sentence, the other half went on to say 'as long as she's available for the hours she agrees, and is ready for her next booking in a presentable manner.'
I didn't quote the rest of the sentence as it wasn't relevant to my point because I disagreed. 'Presentable manner' is subjective as outlined in the reply above as per the difference between a wet wipe vs a break, a shower, and getting herself ready. Again, if it's not an issue for you, that's totally fine.
Another thing, and this won't apply to all girls or all situations, but with some of my regs I enjoy getting them revved up, and I get a lot of enjoyment from girls who will climax from RO, who get into a snogfest, fuck you back with passion, etc. If she's running a conveyor and has been shagged senseless for 5 continuous hours, the session I'm hoping for isn't going to happen. With this in mind, for certain girls in particular, I know when, both in terms of days and times, I should see them.
This is more of what I'm getting at, and it's subjective. The only reason I'm even commenting is because a blanket statement such as above, doesn't work for everyone, and hence why there are guys on both sides of this argument, and for a number of different reasons. It doesn't have anything to do with giving a toss about how many guys she shags, it's about having her at her best when she sees you.
