Unless something is 100% positive, some jump to make a negetive.
BUT not to say it isn't an opportunity to think, ok am I warm enough, do I look like my photos, do I rush things, do I pad out the booking with enough sexual engagement< . If you can honestly say you feel you provide a good service then it's just a matter of his opinion and he was probabley looking for a porn star type rather than a vanilla type, which does tend to be the main culprit of negetive reveiws I've seen. I will never begin to understand how different peoples opinions can be. What can help is googling an escort you admire then no doubt there will be a negetive if they're popular. Take a look at all your lovley feedbacks, i'm sure you have some on the forum too. It hurts for sure but take solice in the idea that it's your work personna and not you.
I could probabley turn around and give myself a bad reveiw for a few one off bookings where we didn't vibe or I wasn't on form. You are human, chill, i'm sure your service is on par 99% of the time
There are folk who start stuttering and think i'm beautiful and their are guys who think i'm butt ugly. Each to their own, it's a concept that needs to be grasped in this line of work or in general really. Don't let it get you down. Feeling down about your services = less money and hey, success is the biggest fuck you.
