Bumps and spots on my penis. What are they? Should I be worried?

First picture is something I posted before. These spots don't hurt or anything, but they have been a cause of concern for me in the past few months. The next three photos show some bumps that have appeared on my glans quite recently. What are they? Does anybody know? I'm 21 and have never had sex, but I'm embarrassed about these and also worried. I'd truly appreciate it if someone helps me here

Okay, what you need to FULLY understand is that if you have NEVER had sex the chances of you having a problem issue with your penis is extremely low.
What you see on your penis is simply a natural set of developments to YOUR penis - every penis is slightly different.
The lumps, bumps and spots that you see are what develops following the onset of sexual maturation, this is a process that usual is complete by the age of 25 or 26 YOA - so there is time for more like this to develop further.
So, yes, they do not look particularly great - but many men get these very prominently in comparison to what you have.
Learn to chill about it, they are a natural part of who you are and what your body looks like …

Thanks man for your time and for putting my mind at ease. I truly appreciate it. I’m generally an anxious person and I think I should do something about that. Thanks again
