Do i have a nipple problem? Advice please

I'm in my 20s. One of my nipples is slightly inverted and the nipple has many little, very prominent bumps and ridges (like mini peaks and valleys). Whereas the other nipple has the usual smooth nipple skin that most people seem to have.

I was wondering, does anyone have a nipple that has lots of bumps and gaps between the bumps?

When my SO sucks this bumpy nipple it quickly feels raw, especially in the ridges between the bumps.

I haven't been able to find any info or photos similar to my condition on google. I have searched through breast illnesses and cancer info too but haven't found any images or description similar to mine.

Help, please. 😅😳🤔😬🙈
