I noticed this cut yesterday. There was no prior blisters or ulcers. They don’t have any fluid either. It randomly appear there. I don’t have them anywhere else. I did wipe with an antiseptic wipe yesterday before giving a pee sample. I do remember wiping rough. Then last night I noticed irritation, checked and I saw it. I haven’t had unprotected sex in awhile. I did receive oral few weeks ago.
