Keep in mind that he just might be curious what
breast milk tastes
like. You could ask him that. If he wants
to try it just
to see how it tastes, you'll probably have a pump, right? or be able to hand-express a little into a cup, and just give it to him. If he insists he wants to try it "from the source," you might think he's doing it for erotic reasons, and that is why it is bothering you? Ask him. If it is an erotic interest, then think over how you feel about that.
