Numb breast?

Okay I’m going to start this of by saying that my breast was never super sensitive before I had my baby. I never had any sexual pleasure by them being touched or anything.

After I had my LO (5 months ago) and started breastfeeding my breasts have been numb to the touch. Like.. My LO can grab them with full force or I’ll pinch them, nothing. I can feel my nails if I scratch them but it’s not an intense feeling or anything. Should I get this checked out or is it normal?

It doesn’t matter if I’m breastfeeding at the time or not. My nipples are normal and I can sometimes feel my let-down but that’s it.
