OP, this is something i have often wondered myself. my default mode is that it is all just lip service, but i have difficulty keeping the disbelief off my face, which usually leads to the SP asking if i do not believe her, and quite a few get offended when i answer in the negative as i assume they say the same thing to everyone else

if that makes you feel like you are a loser, you are in good company

An SP told me once that an unprompted compliment from an SP is likely to be genuine. If you give her RO and she compliments you on it, she means it. if you ask her first, she does not. if she thinks you are shit at RO, she won't say anything about it at all, et cetera. Others i have asked, seem to be in agreement with this.
Escorts are providing a service, and like most service providers they want repeat business, especially if you are a good customer, so why would they not attempt to entice you back with some honeyed words?
That aside, handsomeness/beauty is in the eye of the beholder. you are doing yourself no favours by going into self pity mode whether that is inside or outside punting. the vast majority of SPs do not care about your looks, they just want you to turn up and leave on time, pay promptly, don't stink and clean your arse. Take that from someone who is definitely not a 10, but is a fantastic 5
