Concerns about skin around the rectal area

Patient: Embarassing question which is why I’m trying online. I’m wondering if you can cause damage to the skin around the anus if you wipe too much and/or too hard. I’ve noticed some small harder bumps, almost liked callused skin, forming around there. It’s not too pronounced but it’s concerning me. I don’t think they are warts, but am I wrong? And how can I get rid of this?

Symptoms: Small bumps, painless
