i cant tell. i would need more background information. it would be related to rough sex, so perhaps trauma? not sure. i would go to your primary doctor or sex health clinic to be on the safe side.
idk if my skin had a bad reaction to something or what but it doesnt hurt unless i press hard on it, it never bled. i noticed it on wednesday . start as a small scab, i showered and it looked like the pic above. yes i have been having unprotected sex i admit
okay. did it blister prior to the formation of a scab?
it was a scab first then open sore
if it now looks like this, i think you're okay. cause it looks like it healing. but i would still get it swabbed to get you the most accurate results
