Im 21, male and recently I've noticed there are some bumps, search what they could be and came across this thread. I have tired to poke at it, not too hard just lightly poke and squeeze it abit and it doesnt hard nor itch. The are white/yellowish in colour they dont hurt when erect or anything. Its just there as bumps and I assume that they are fordyce spots from what I gathered, but there is also 2 bigger bumps around an inch in size and is hard, a turtle-shell shape and it also does not hurt, not red and does not itch. They are on the shaft, a bit worried. Sounds like they are harmless but still on the edge
