Use a hand mirror to take a good look at it and google perianal crohn's skin tags to see if it matches with that or pics of hemorrhoid's to see if it matches that instead, they can even confuse the average doctor so it's best you look yourself to see which it resembles...or as someone mentioned it could be an abscess but those don't tend to be soft and squishy and they usually have pain and look like a deep pimple often with a white head on it.
