Had pimple like lump, about the size of a dime, below the skin, in the area behind my testicles and in front of my anus, in the perianal area.  Had for about 1 to 2 weeks. Thought it was a pimple, so I kept squeezing it to pop it.Finally, it popped and blood, only blood came out. Is about half the size now.
Welcome. I have gone through your query. It is difficult to diagnose without examination, so either I would suggest you to upload the pictures or see local doctor for examination. It might be folliculitis, but need to be examined. I would suggest you not to squeeze it. Hope this helps. Take care
