I like this answer. It touches on the weird entitlement that -everyone who is not in an age-gap relationship- thinks they have to judge two consenting adults.
There is, you are so right, a history of older guys with money effectively 'buying' younger women with the security etc. that they offer. She wouldn't be naturally attracted to him but will put up with him because he pays for everything and will not be unfaithful to her and will feel super lucky to have her.
Even in that dynamic, though, she's made a choice. I personally really could not be with a guy who I didn't find attractive just because he pays for stuff. I would not. I think that in many young woman - older guy relationships there is a care/attraction thing that works. It isn't just about money, it makes her feel good.
As for the OP's dilemma of older women - younger guy.
I have experience.
Do an experiment, like I did: put some nice recent photos on hinge/bumble/whatever mainstream site. Set your age range 20-50. In my case, this results in 85% under 25s being super nice to me.
This isn't about money. This is a genuine compatibility. OK, so right now I can't have a full-on life relationship (I had that, no comment). But I do want someone to enjoy the woman I am. And omg these guys relatively fresh on the scene so do.
It all started because one approached me in rl, I was horrified and said are you insane, but eventually said yes. Then I understood.
There is so much prejudice about this, and women are yes totally made to feel as if it is unnatural and predatory. I have never in my life approached a younger guy. They do everything to charm me. Seduce, groom, me. Because they know I will worry and won't ever imagine they would want me. Because as women we are just so deluged with these images everywhere of how we should, in particular, look.
Women live, just like men, if we are lucky. They live, they feel, their bodies become etched with the life they lead. We are pregnant, we give birth. Who knows what is done to us for the baby to be got out. Who knows what we might go through night after night. Who knows. But if at 40 plus a 20-something guy says wow. Please. You are amazing. You don't even realise who you are. And wants to respect and be close to us and make us happy then ........
why not?
Don't feel bad. 25 omg he's been a man several years by now. `Nothing matters but the feeling between the two of you.
People are comfortable with so many variants of sexuality, and there is a lot of talk about it being absolutely fine to be yourself. But I think judgementalism around older woman-younger guy is shockingly entrenched.
Just be happy, no you are doing nothing wrong, you are not predatory, you are humble, and if they guy likes you and you him, hey.
