Recently found out husband has breastfeeding fetish

First let me say, he does NOT get turned on when I’m breastfeeding my son. He gets turned on by the thought of him himself breastfeeding.

I don’t know how I feel about this though. He wants to breastfeed off me, but I feel weird because I feel like this milk is for my son and I’d feel bad giving it to someone else if that makes since?

Anyone else’s significant other into this?
