Is your S.O curious about BREAST MILK

I'm asking because my fiancé is so weird to me now with my first child my boobs leaked a lot and peeled as well so I wouldn't let him suck them because of peeling dry skin. But this pregnancy he is attaching himself to my boobs they aren't peeling at all. But leaking so!! And he just randomly asked one day I was in the shower baby can I get some of your milk??? I wanna see how it taste I laughed and said no cause I thought he was joking. But now when we are having sex he grabs them and just sucks and I'm kinda lost like it stil feels good but I'm milking 🤢 and he says it doesn't bother me I can barely taste it. Today when he got home yesterday he wouldn't leave me alone I'm starting to think this man is a freak and not the good one
