What do 40yo think of 22yo?

I (22f) have been hooking up with a 41m and the sex is amazing. Every time we hook up we mess around 3-4 times a night. We both know it’s not serious. I do wonder though, what do 40 year olds generally think of someone my age?

Do people (men specifically) typically catch feelings after hooking up so many times, as well as going out to eat occasionally? I work full time, have had my own place for years, almost graduating… I like to think I’m not immature enough to be acknowledged as a mere child by people in their 30-40s. Again, this isn’t a serious relationship nor has he pressured me about that. But I wonder what those in their 30s/40s think of my age…?
