My male coworker calls me ‘girl’

I’m 35f and hes 29m. We are both the same management level ( he has been with the company for 6 years and work his way up, I just started 3 months ago)

He has made comments about me being a ‘girl’ and the other day said this girl is really good at that, so he doesn’t mean it in a mean way I don’t think. But I feel like I’m older than him and deserve more respect.

Am I being over sensitive?
