Breastfeeding

I’m really into breastfeeding my boyfriend but he’s not really liking the idea of it. I really want that bond with him and it’s hot too. What should I do? I am also wanting to breastfeed on someone else but I am in a relationship and don’t know what to do. Should I ask him about me doing it? For me to do it to someone else it’s just for the comfort not sexual pleasure. But I want him to do it to me for the sexual pleasure and comfort for us both.
