My thought is, why do you need to start a thread on it?
Clearly you are aware that a majority of experienced members on here don’t follow your routine and you’re maybe wondering if there’s something you missed…
You’ve got half of it right in my opinion. Make some notes while it’s fresh in your mind. But just some notes, don’t rush to post them. I leave it at least a day or two (depending on circumstances maybe a bit longer). This is both for anonymity as you rightly guess (and personally I think you underestimate a p4p’s ability to identify you from a review); but secondly, precisely to let that ‘savouring the moments’ settle down or pass.
If one pays good money for a product or service and it doesn’t immediately seem faulty then there’s a tendency to over-rate. It justifies the expenditure, congratulates oneself on one’s choice, time and effort, and offers a chance to talk about it. After a couple of days, comparisons sink in and it gets put in clearer context. And after all, it was just a paid shag, not some amazing cop off with a hot chick. You got your balls emptied. Congratulations.
