Bumps on penis are they warts?

Hello, about 3 weeks ago i noticed a couple of whitish almost flat bumps on my penis. I didnt think much of them but another one seems to be showing up now.

I have had an STD check recently (just because i was curious, not because of any symptoms) and all was clear, it didnt check for genital warts though.

I did have unprotected sex about 4 months ago.

So, hoping someone recognises what these are and can advise.

Thank you.
