If you are handling them more (inspecting for hsv) this will surely aggravate the skin causing itch and mild burning.
Your welcome. It is mental and that is completely normal. When someone tells you they have something on e you've already starting fooling around can throw you for a loop. The important thing to remember is hsv is not a super infectious virus and you were at no risk. I understand Der stand your concern and I appreciate the anxiety you feel.
Symptoms can be quite harsh or very mild. The point is you had zero risk of contracting the virus
You are at zero risk for genital hsv. No std will transmit through clothes. Even thin panties and that includes hsv. Even if the panties are wet from vaginal fluids. You can breathe easy as you were not at risk.
