I too have been struck by how many work in the "caring professions" - nursing and similar. Natural progression I guess.
Suddenly remembered (the older I get the less I remember) a few things besides the fact that there is no single reason why we - or WGs - do things.
My first marriage came to an end when i met a retired WG - ot Party Girl as she called herself ("I wasn't a prostitute") she claimed. She had made a phonomenal amount of money - all pissed away on drugs. She only quit because the Old Bill fitted her up and she was on probation. She was just in it for the money and she hated her clients. She was quite proud of the fact that one - very famous - died of a heart attack when taking poppers in the bath, a habit she introduced him to. After we split (because, believe it or not she was insanely jealous) she went back on the game.
More recently I became friends with three girls. (I only started punting i8 months ago). One from Romania does it to help her family -- she showed me lots of pictures, and you could see they were her family as she was in some of them. I never asked her what else she had done for a living but she told me she startd as a WG at 16, is highly educated, extremely attractive and very funny, though not the best I ever had by any means.
One who is English works and loves doing it. So much that so although she has a SD who pays her good money every month NOT to work whe does it but keeps it secret from him. She insists her clients don't rate her on AW.
Another, also English, tells me she loves "the idea of not knowing who's going to come through that door". She works part-time in admin in a hospital. Recently she had a bust-up with her partner who owned the flat she works from, and ws really upset when she couldn't work - they've made it up now and she's back on the game.
It takes all sorts in this as anything else. Right now I'm in a "normal" relationship which has convinced me not for the first time that punting is cheaper. Admittedly the gf does almost anything kinky with me but it takes up a lot of time. It's cheaper and just as good by the hour.
