Sperm on Thumb

[HiDoctors]

I ejaculated some days ago and I think some of the sperm got on my thumb today I found these bumps or tiny holes in my skin. It's been there for days how do I get rid of it!!

The Process of it
1. Itching
2. Hard Callus like
3. Skin kind of cracking

The sperm has nothing to do with it. If sperm was that acidic, women would not get pregnant.

Sounds like you have a fungal infection or an allergic reaction to something you touched.  Also possible that  you touched a chemical, or that it's eczema or psoriasis.
