This sentence basically summarizes the rationale for all my 3 friends with sugarbabes.
The chicks set their requirements ($$$, what they can and cannot do and availability), the dudes see if they can accept it and done.
One of the arrangements that I remember is 2 visits a week and semi exclusive, (meaning they are allowed to have BF, but no other sugardad) and during that time, they do whatever the dude decides. It can be either eating out, go to the theater, some random activities or just netflix and chill. Sex is usually involved but not always. Again, totally depending on the dude. And when sex takes place, no need to worry about whether you are satisfying the lady. Just whatever the dude wants.
All 3 of them, while not hot guys in any way, they are generally in shape (all go gym regularly and sport activity of some kind like skiing, biking... etc) and if they wanted to find some chicks, I'm sure they could one way or the other.
But they are just done with the BS. Having to endure whatever craze their chick has (and honestly, I have yet to meet a girl who isn't crazy... just different degree), responsibility (whether social expectation or whatever) and having to compromise in any way to make their lady happy. The sugarbabes are not in their life at all. They might bring her to a social event or two, but basically they are never anyone with title other than +1.
Instead, they get to bang what's some dream girl for a lot of nerds, zero commitment or responsibility other than $$$ and when they no longer feel attracted to the girl or want to try something else, a few clicks and it's done. He can be with a busty more mature woman this month and a skinny young college girl the next.
They call it "happiness as a subscription."
And let's be honest here. How often would you find a true 8+ girl on dating apps or in your social circle? Unless you are in certain field, the chance of meeting one is already low enough, banging one is near impossible.
I am in no way having any desire to be part of such. But I can totally understand their rationale. I wouldn't want to deal with the whole dating BS if I had to start all over again. I would die alone

before going through the dating BS nowadays.
