Expert Q & A Answers About symptoms

I have a couple bumps on my penis, but they don’t look like pictures I’ve seen of genital warts. What else could they be?

About a month ago, I noticed a tiny bump on the head of my penis. A week ago, another tiny bump appeared beside the first one. I've seen pictures of genital warts, but my bumps look nothing like the pictures I’ve seen. Do I have an STD? I’m concerned.
