Hello there,
I had unprotected sex 3-4 weeks ago and have now just developed two circle shaped ulcers. neither were blister and have not had any fluid. I am guessing its is HSV or something else. I had contracted HPV many years ago have never tested positive for anything else or had any other symptoms. my last health screen was was Dec 20 2019 which was clear of everything. 3 weeks ago was the only sexual partner since.
ill attach a photo to help.
