HELP - what is this lesion? (Pic included)

[WorriedSick2020]

Name change as it's a pic of my bum cheek.

Not painful unless I catch it when wiping, just got DH to have a look and to my horror it's this. Does it look like an ulcer? Why would I get an ulcer on my bum cheek?

Thanks everyone for your help and kind words

So glad you've had it checked out xxxx

What was it?

well done. not nice to have lots of people ogling your bum, even for a very good reason.
