Strange rash-like blemish on the the shaft of my penis

over the past month, this rash- like blemish has developed on the shaft of my penis. The last time I was sexually active was about two months ago, so i can’t be sure there is any correlation between that and this rash thingy. a photo is included, any help figuring out what it might be would be appreciated as i am a truck driver with limited time to see a doctor. thanks

thats nothing to worry about might be some skin irritation if u have used condoms apply t-bact and you will be fine
