So I have this currently on my bum cheek about 5 or 6 cms’s from my anus. Nowhere else. I have had it before. I am very sweaty down there and get quite damp between my legs/buttocks and I do shave this area. I don’t feel unwell. No pain urinating. It doesn’t get any worse than this and is only slightly painful when my clothing rubs against. I get it quite regularly in roughly the same area and have on occasion had it on my bikini area, again where i shave. Sexual health are not convinced this is Herpes but not sure what else it can be
I get the picture isn’t great, however it is quite small as you can see from the comparison with my nail.
I should have said they tend to disappear after a few days, 4 or 5. No ulceration. It kind of just dries up and goes away.
just bumping this up a little in the hope someone sees it 
This is a picture of the sore on Tuesday.
and this is it Wed. I caught it when wiping and the white part came of and I was left with this. No discharge and it is healing. No other sores at all
