So Recently I Stared Spraying My Underwear With Cologne For

So recently I stared spraying my underwear with cologne for the past 2 weeks. But one particular rime I had sprayed it directly onto my pens. Each time I did feel a little sting but nothing too serious until about 3 days ago. I noticed a small red irritation around my Urethra area. I don't have any discharge leakage but I do feel a slight sting when I piss. I have been using steroid cream and ibuprofen and it has been feeling better. Just wish I knew cologne had alcohol in it before I started spraying myself.

I have also had unprotected sex with my partner which is clean, but should I be worried about any STDs or UTIs?
