James,
I can understand your concern about your symptoms. I urge you to consult your doctor, who would be in a better position to address your concerns, after thorough physical examination and laboratory testing.
When I was your age I had the same concern. I tried to squeeze puss out of them too (and that caused an infection ... so don't do it anymore). I went to the STD clinic (even though I was still a virgin) and was told they are normal, some are just more prominent than others. Don't worry yourself.
Take care.
