I feel neither guilty nor proud about seeing escorts. I treat it as an act of self-care: I'm a person with sexual needs and I don't think there should be any particular stigma attached to having those sexual needs met, as long as it's through legal and consentual means. In return I think I'm a decent punter: I arrive on time, hygienic, with the correct money, I treat the ladies courteously, and I fuck off on time.
At the same time I agree with ethical punting. I've never knowingly used an escort who was trafficked, or showed any indications of working under duress. Have I punted some moody cows? Sure, but it's a job, none of us are entitled to a job which is easy or enjoyable 100% of the time.
I've also seen a few ladies who, let's not be naive, clearly had issues. Mental health, alcoholism, substance use, whatever. Those issues are by no means unique to sex work, but probably over represented in the industry. I've tended not to make these ladies into regulars. I don't necessarily think punting these "troubled" ladies is inherently exploitative, but it's not great for the conscience either.
