<human>: I have had unprotected sex the other day and noticed the same day (within hours) that I have what almost looks like a rash on my penis on my foreskin, it does not itch nor is it painful. And now I have a lot of small white bumps as well. I keep it as clean as possible.
<bot>: Thanks for asking in Chat Doctor forum In short: Unprotected sex with unknown person is dangerous to healthExplanation: As per your explanation it may be simple mucosal erosion which sometimes occur on glans due to Chat Doctor.  Your white bumps may be sebaceous gland visible on your glans/scrotum. These are harmless as such, and you can consult dermatologist for this if you are not convinced.  Give rest for 2-3 days, I think your rash will subside by itself otherwise visit a dermatology and undergo test for STD.  Good luck
