Boob size off handed comment

Renee

I’m recently divorced after 10 years of marriage, newly dating a guy who has described his type as blonde and big boobs

I’m brunette, tall but athletic build, not busty

Dating guy made a comment recently after accidentally elbowing me in the boob while watching a movie of “just checking there’s something there”

Is this going to be a tiny (boob) red flag, or just an awkward comment of no real significance?
