Bumps on your penis can be caused by a lot of different things, not just STIs (sexually transmitted infections)! One common possibility is something called pearly penis papules. They are tiny bumps that appear on your penis, usually in a ring around the head that about 1/3 men get. They are harmless and cannot be transmitted to other people.
While this is one potential reason for these bumps, we cannot confirm if this is the reason for you over the internet! If you are experiencing discomfort or have further concern, please reach out to your doctor to check and get treatment if necessary!
