Blackhead bumps around anus

Ok, First lemme start off by saying by butt usually sweats alot. Everyone once in a blue moon but anus will start itching, typically i scratch it and after washing really good it goes away after a day. Well yesterday i got a wild hair and decided to take a look at what the heck was making my arse itch. Using a mirror i was able to see some blackhead like bumps around my anus. I popped a couple of them and they just appeared to big big blackheads. They were very liquidy - I would compare them to a blackhead type substance. Shortly after i popped them the itchyness went away. The very next day i checked to see what was up - and no redness or ichyness was noticed.

Have any idea what i may be dealing with?
