Does he belong to the streets?! He refuses to call his girlfriend his… girlfriend.

My boyfriend calls me his lady friend and refuses to call me his girlfriend in public. He thinks it makes him sound like a simp when he calls me his girlfriend. I feel like when he calls me lady friend that it makes me sound like a floozy and not someone he loves. Does he belong to me to the streets for calling me his lady friend? By the way he’s 31 not some old man. Ahoy!
