I've tried to plan punts, and booked specific things like anal ahead of time, but tbh its so random how the erotic imagination works that scripting usually fails when it encounters reality.
For example, there was a black British escort who said she liked to be talked dirty too, so I deliberately booked her with that in mind. However, when we met I just couldn't get into it - the body language coming off of her said she was uncomfortable as well. So, I jacked it in and had a perfectly pleasant professional shag, which as it turned out was exactly the sort of detached clinical sex we were both comfortable with; I'm not trying to diss her, once we both stopped trying hard and just went at it, the booking actually totally turned around.
Same thing happened the last time I went swearing I'd go for CIM; I had some great head, and then finished in doggie, which I never do - seriously, it had been years as it isn't my favourite position. Generally I find that I need to be having sex before I 'know' how I'm going to want to cum. The only exceptions are when I get the occasional craving for a handjob or a blowjob specifically, and when that happens I never book a FS provider, I go to a Chinese place or book WGs who offer 15 minute blow-and-gos.
