4tplus this subject interests me too as I've also encountered the wrath of self-appointed nuns for having a conversation with a younger man who totally did all the running, and who I had no interest in and had to repeatedly put off. And not one younger man has approached me.
I would say that in your 40s, you may notice a sudden surge (!) in interest from much younger men. Especially if you look as if you're in your mid to late 30s. I decided it was a biological phenomenon, because it's last chance alley for the female to reproduce, and the younger the sperm the better the chances. They are naturally drawn to you.
It's also very flattering at a time when we worry we might at some point lose our appeal. And there's a directness about younger men which can just fizzle out in men over 40.
But the violent outrage of some women about women in their 40s recognising the advances of men in their 20s is a real shocker. I've encountered it too. It's really upsetting. Actually I find it obscene. They are the ones with weird minds. An adult is an adult and I know quite a lot of couples where eg the guy is 60/70 and the woman is 30/40 and that's apparently fine. Guy being 56 and woman 38 seems like nothing. But when you shift it all to the reverse - with the woman older - apparently it's sexual perversion in the extreme. Bollocks. 😉
And I've found the very people who behave as if you're a sexual deviant just for recognising the come-on from a younger man (not even acting on it), are those who coo and comment approvingly on the man of 70 with wife of 41.
It's actual a form of sexual misogyny and very unpleasant. And it's stupid.
So don't listen. You've done absolutely nothing wrong, you came here for advice, and the Matrons have thrown their aprons up in horror.
Sam and Aaron Taylor-Johnson are a great example. He clearly adores her and appreciates the treasure of a woman who's lived something. She is glowingly happy with a husband who loves her for who she is. She was born in 1967 so 52/3 now. He was born in 1990 so 29/30. They married when he was 21 and she was 45. And it's nobody's business but theirs. I've always admired his maturity. And he's not the only man in his 20s who is old enough to make his own decisions.
It's up to them. Just as you enjoying a conversation with a younger guy is up to you and him. Do not feel tainted or worried. Ignore stupid comments. Be who you are and live now, especially since the virus is a big example of how we might not be here tomorrow.
