I have dated older men several times.

One time I dated a 45 year old, I was 24.

Then, I dated a 53 year old when I was 32.

The 53 year old man had health issues, and in my opinion, was finally looking to settle down because he wanted a nurse maid to take care of him. He'd had a stroke a few years earlier, something he didn't tell me and I found out on my own later.

So, I would be wary in general of why a much older men is interested in a young woman. I did not want to be anyone's nursemaid.

I don't think of 40 or 50 as "old" but maybe a little too old to be dating a woman in her 20s.
