I have had sex with 2 woman both were with protection but the condom broke and alcohol was involved this was all in the past 3-4 weeks.
I haven't noticed anything weird like pain while urinating or any burning but I discovered the following on the back of my neck. I did not know the status of either people and they were one night stands.
Here is a photo of what I see.
