red sore on the edge of pubic area. is it herpes?


noticed this red patch outside the vaginal area a few days ago. at first thought it could be razor/stubble burn since its well outside the labia area. it looks like some skin flaked off but isn’t healing into a scab which is making me worried that it could be more serious. it doesn’t look much like a blister or welt - more like a patch or raw skin. any advice?
for context, i’ve never had an STI before, had the same sexual partner for 6 months & we always always use protection.

get it swabbed
