Red, raised patches on the head of my penis! AM I DYING?!?

For about 2 weeks now I’ve had 3 red raised circles on the head of my penis, 2 have gone away rather quickly but one seems to want to stay and has grown a fraction of an amount. the patch is not, itchy, nor is there any pain, no puss or discharge coming out. i feel fine as well, so im not quite sure what to do , it very well could be an STI as i am sexually active but i have a feeling its not! someone put my mind at ease, please.

here is an image if the affected area, hope that helps

I very much doubt whether this is a specific indicator that your life is at risk! What I do is for anything that looks like it should not be there is to try a tiny dab of pure Liquid Antiseptic on it (TCP if you are in the UK). Do this 2 or 3 times a day and most likely it will heal within 3 to 4 days …
