If your of an escort who enjoys what he does, and enjoys his time with his clients - it shouldn't matter if the client is overweight or not.
 
A "true and humble" escort doesn't and shouldn't discriminate over size, race, or creed of any kind.

'warn' implies that it is a negative ... I would rather 'inform' than 'warn'.

Yes.
 
Here's one anecdote I can kind of remember from years ago. I showed up at a door of a client who was pretty seriously overweight. He explained to me that he realized at some point it made sense to tell escorts about his weight before they showed up at his door, because several times he had been rejected by escorts who showed up, took a look at him, and said the appointment was not going to work. In some ways I give credit to the escorts, who could have chosen to simply try to stay and rip him off without really providing what the client wanted.
 
To broaden the answer, here's another anecdote. I had a client who was in really good shape for his age - 70's - and liked to pride himself on looking like he was "young 60ish." Having said that, it seemed like he felt compelled to act like a 20-something sexually. He also told me that his expectations for long sessions of flip/flop anal sex so intimidated some well known escorts that they couldn't get erections around him and wouldn't let them hire him, usually after they had tried and failed to meet his expectations (at least by this client's account).
 
During this same period, I recall being hired by a client one night at his hotel who was overweight and could not get an erection due to surgery, but liked to be fucked. He said something like this to me at the start of the session: "Steven, I want you to know that I am not going to get an erection, and you are not going to see me have an orgasm, but I will really enjoy getting fucked by you." He was warm and fun and relaxing to be with, and it was a very fun appointment for me and I think him.
 
I recall thinking at the time that as I age, I hope I age as gracefully and with as much self-acceptance as the second client. And I felt sorry for the first client that he put enough expectations on himself that he often felt let down. And I do mean put expectations on himself, not the escort, because it seemed like at some deep level he really wanted to feel like he was much younger than he actually was.
