Touching

I am only three weeks post partum with my second child. My boyfriend constantly wants to to touch me especially my boobs I’m breastfeeding and they’re extremely sensitive especially my nips since baby is a little rough when matching. My boyfriend gets mad and rude with me when I tell him to stop telling me that he knows when someone is and someone isn’t interested in him. He’s not understanding at all and makes me feel like I’m a bad person because I don’t want to be touched.
