What is going on with my shaft?

my girlfriend has been my only sex partner, and I always use a condom during sex, only thing she gives me oral without a condom, but a while ago I noticed small bumps on my shaft, sometimes they are white, sometimes red, sometimes skin colored, sometimes not even noticeable.

they have no itch or pain, I may have a latex allergy too, because since using a condom (I was a virgin before I had my gf) I’ve noticed red bumps on my head of my penis too. Again no pain or anything.

i noticed after getting out of shower the bumps on my shaft are barley noticeable. What are these?
