alright im 17 years old, never had sex before but am worried about my penis..today i noticed on the tip of my head on one of my urethra, there is what looks to be a bubble of either puss or idk, its white and not very big but its the first time ive ever seen it. And this isent new but about a month or two ago i started getting little while kinda pearly looking bumps under the head of my penis and idk what those could be? they look like acne but i have no idea? i have no pains or anything wrong with my penis it feels normal ive not noticed any odd feeling or anything down there, but if anyone knows what this is or could be i would appreciate it.
