Hi doctor I had unprotected sex about 4 days ago

Patient: Hi doctor. I had unprotected sex about 4 days ago and 3 days ago i started having little spots on the tip of penis. Im trying figure it out what it is. Help me please. It doesnt hurt when i go to the bathroom. And it itches a little bit. And at times. Im uncircumcised. it kinda looks like a rash. But i just wanna make sure, to make sure im not in danger.

Doctor:
