On AW quite a number of women say they won't see blokes of less than a certain age - often around 35.
I find that attractive on the basis that it seems to indicate a maturity on the woman's part so maybe I spot more of these women than others.
Restricting herself to older men is one way of discouraging young turks who have no idea how to behave. It also moderates demand of course - again indicating the woman concerned is likely not one who will see more than two or three clients a day. (Ticks Uncle's boxes.)
I recall being told by a MILF in the Y & H region whom I saw a couple of times about 3 years ago that she had a lower age limit - 25, I think - which was there for two reasons: she found the attitude of many of the under-25s she'd seen "disrespectful" to a woman old enough to be their mother; and more pragmatically, she had daughters in their early 20s and didn't want lads whom they knew - and she might have seen socially - booking her under her working name, then finding out that they'd already met!
A small number of women quote an upper age limit, sometimes below Uncle's age. I've either talked them round or said nothing. In these cases I ask them (mid-thrust) how old they think I am. I'm usually very pleased at the response but I take care of myself.
None of the above yields an answer to the 2nd question above - merely some factors to be considered.
But then who really cares? What really matters is whether you can still find satisfactory women at a sensible price with whom to engage.
Have a nice weekend

When it comes to upper age limits, Uncle, I'm afraid I don't have your 'cojones', as they say in Spain; I've always taken the view, 'her body, her rules'. Although I did once ask a fellow-punter I'd met socially if he'd ask someone he'd seen - and I'd have liked to - if her rule was inflexible. The word came back that it was.
I've only seen one woman who said, "No over-60s" and that was a few weeks before my 61st birthday! During the punt, she must have suspected I was above her age-limit and wasn't amused when I said I wasn't - a matter of weeks. The quality of Service - already not terribly high - deteriorated ever further from that point.
