Am I being too picky?

I’ve (21f) been starting to date again recently after getting out of a long term relationship. My ex (40m) was 19 years older than me and we met when I was 16. I don’t necessarily know what’s “right or wrong” but I do know based off of that experience I don’t want to be with any guy who would be willing to date any younger than 18 (including not waiting for them to turn 18.) Ofc there are exceptions for like the half your age plus 7 rule. But like if a 24 yo is willing to wait for a 17yo to turn 18 I’ve been shutting it down. So far I’ve asked several guys ranging in ages from 23-25 “would you wait for a 17 year old you really like to be 18 before being with her?” And they’ve all said yes.

This can’t be most guys right??

Am I being unrealistic?

Ofc I know a 25yo with a fresh 18 yo is different than a 37yo but still. I just have way too much anxiety surrounding that stuff.
