I am one of the more mature clients like the op and I have no problems with the younger women, if they are advertising, 18+ and fit my wish list physically and sexually I will book them.
I had one in January, at the time of the booking in a hotel I was concerned as she looked too young so I asked her for ID, she produced her Provisional Driving Licence, at the time she was 18years, 2 months and 4 days old!
After the 1st pop I asked why she was doing this? She explained that she had recently split up with her BF after she caught him cheating, she was royally put out that he had slept with a fat girl (her words) and she was so slim, she also needed the money for some gigs she wanted to go to! And had for a long time fantasised about sex with older men, she was actually quite clued up and only intended to do a couple of jobs and I was her last client. I asked her at the end if she had enjoyed the experience? She said she now understood that sex was more than just getting her pants off and being humped silly and that she now knew what an orgasm was! So it was a positive experience for her and not just a cash transaction, which she was very much undercharging for.
True to her word she took her profile down a couple of days after I saw her.
