single red bump/dot on penis head after masturbation/sex

Hi all, so for the last couple of months I've noticed this single red dot/bump on my penis head. The dot itself isnt itchy or painful, and would disappear and sometimes reappear after having sex or masturbating. I'm not sure what this thing is. I've found tea tree oil and coconut oil helps to get rid of it. But it looks like its a temp solution. Any idea what this thing is??? should I worry??

Spots or bumps like this are very common and is unlikely to be caused by anything problematical. I would put it down to a skin imperfection.
Solution, do NOT have sex or masturbate for 3 to 5 months and see if it goes, otherwise you would need to put up with it.
If you are suspicious you have an STD / STI - although this is not a symptom of such - go get tested
