On my penis, more specifically my glans, I have red circles/buttons. What are these?

Good evening sir,

It could be many things (heat pimples, irritation from sexual intercourse, inflammation related to the presence of yeast, syphilis, etc.).

To find out the exact cause of these pimples, you would have to show it to a doctor (he is the only one who can diagnose the situation).

So, I recommend that you consult in the next few days.

Sorry I can't be more helpful at this time.

Happy evening,
