Husband wants to touch my nipples but I HATE it

I remember I used to be “okay” with husband touching nipples when we were first married? I’ve definitely never gotten any pleasure from it, just allowed him to touch. But now I absolutely hate it. They’re sensitive, I didn’t like breastfeeding my first son because it felt “weird” and like too much sensory input, and even when I’m NOT pregnant I have actual nightmares about somebody using scissors to cut them off! AHHH!

Is this really not normal?! Do I need some type of therapy? I’m serious guys. Lol my husband acts like I’m the only woman in the world who could hate their nipples touched. He’s trying to convince me that he could desensitize them for me, but I dread the thought. At the same time I hate feeling this way about them.
