What is this? Should I be worried? STD?

I just noticed these bumps and I dont know if I have had them before. I have been sleeping with a couple of people and one guy told me he had red bumps on his penis. I’m getting tested but I am still nervous. Does anyone know what this is?

hi
I can not see anything wrong
it all looks normal
are you having any pain, burning, itching
any unusual spotting or discharge
