I (26F) met a guy (38M) from online dating. What are some things I should be aware of regarding this age difference?

I met this guy online, he's 38 and I'm 26. We've been talking and going on a few dates.

Our personalities and life experiences are pretty different. He's paralyzed from the waist down, has been to graduate school, is more calm and quiet and introverted. I'm more expressive and extroverted and was never a school person but managed to get a bachelor's degree even after failing a few classes.

He's really good looking and has the most attractive personality.

Part of me feels weird about the age difference, but lately I've also been trying not to think too hard about dating. In the past I was the type to overthink and over analyze everything. Nowadays I'm just trying to go with the flow.

tl;dr: What are your thoughts and opinions on a 12 year age difference?
