Spots on penis glans

It started with the two purple dots and a little red spot about a week ago. Then it changed to the last image the only one little red dot and a few other hard to notice dots. Currently it looks like the middle imagine with a bigger spot. I’m 19, haven’t had sex for a couple of months, completely unsure what they are. No other symptoms besides a reddening of the penis. I’m on no medication. On holiday currently, will see a doctor when I get back.

This could be anything. If you have some liquid antiseptic to hand put some undiluted on after you have urinated, then washed or taken a shower, probably these would clear withing a few days of doing this …
