I completely agree! And what particularly turns my stomach is men (mostly famous male celebrities,) who are 45 to 50 and older, who seem to have women 20 to 25 years younger. (Or more.) It makes me retch. 😖
Leonardo DiCaprio is a typical example. He's 50 this year, and looks it. And whilst he looks OK, he is out of shape and pretty average looking now. Yet he is currently dating a young woman in her early 20s. As much as I've always liked and admired him as an actor, he's actually starting to turn my stomach now and make my skin crawl.
So does every other man 45-50 and older who's dating a woman young enough to be his daughter. Some men (especially celebrities,) are 55-60 or more, and STILL have a woman in her 20s! It's fucking grim!
I don't understand it - and I really don't understand why these young women go with these much older men. Is it really just for the money and the fame? Are they that desperate for money that they would date a man 25 to 30 years older, (or more!) and let him paw her, and put his hands all over her? I actually feel nauseous just thinking about it. 
And as for non-celebs... WHY would a young woman (under 30) want to be with a man 50+ ??? Not only is there a power imbalance, but men that age are mostly fairly unattractive physically. And also, she will end up being a carer for an infirm pensioner, whilst she is still only about 45-50. (Whilst probably looking after their children too, and her parents!)
Fuck that for a lark!
