I have blisters on my inner thigh, close my underwear line, their in 3 sets. 1st patch is of about 4 tiny blisters 2nd patch there's about 7 tiny blisters 3rd is extremely close to my butt and where chub rub would be and it's about 3 big popped blisters with a few smaller ones around it. I don't itch or anything they just hurt when I walk, my thighs touch so ive had chub rub before... Could it be an std? Herpes? I had a new partner.... But I'm his first. Help me please
