I don't think this is a fair question to ask honestly.. I wouldn't call it pathetic, because I understand where it's coming from and I'm sorry you're having this insecurity. For a lot of providers, myself included, enjoyment has nothing to do with what our clients look like, more how we are treated by them and other factors.
If you, and other clients (I often read "she's only doing this for me the money" here as a complaint... I don't like seeing this because it's our job. If you want to see someone who's ''only doing this for fun'' open tinder and try to find a match...), worry that we aren't truly enjoying the experience then I invite you to try and help us find it enjoyable.
Be respectful, kind, have good hygiene and interesting things to talk about. Your provider should have a good time!

also remember we are used to seeing people of different ages who have very different body types all the time, so we end up having a different way of looking at things.
I've heard many providers say that no matter what they can find something charming and attractive about everyone they meet. We are also constantly scrutinized and judged on our looks, so I think most of us don't want to do it to others. I've almost never heard a provider make fun of the way a client looks.
I'll speak for myself, what makes a booking truly enjoyable is the clients personality, and often the conversations. I've had sessions with very conventionally attractive and young clients but I didn't enjoy these bookings any better. Sometimes when certain men know they're attractive, they can act a bit more entitled.. We've all heard ''can I have a discount because I'm cute?''. The answer is no.
