I just feel like my priorities, where I am in life, and cultural reference points are in different places with someone significantly older/younger.

I’m not overly humble, but if an attractive much younger woman contacts me (as has occurred a few times on dating sites), chances are it’s a scam.

The one thing I'm certain of is this is so different for everyone, and even for each relationship. I've twice been in a long term relationship with somebody 10 years younger. The first one was great and we're still best of friends today. The one after that was a disaster. Overall I'd say for me a 10 years difference either way works, if it works for the other party. Much more than that and I think I'd maybe feel uncomfortable. But you never know. I have friends who've been together about 15 years with a 22 year age gap.

I had a relationship with a woman 17 years younger and it worked fine but if she hadn't pushed it , it wouldn't have happened. There's a bit of a disconnect with history, songs, movies etc but these days those things can be caught up on. If the younger person chooses it, you should go with it. It's flattering and as long as they are old enough to know the pitfalls, it's no different than any other relationship if you two connect. Just my two cents.
