lump in/on anus. Hemorrhoids?

Hi, quite embarrassing but I have noticed a bump/lump on my anus (may have another one as well, cannot tell), it is a bluish color and does not hurt (unless I put pressure on it, but even then its only a minute amount of pain). I haven't really felt it otherwise, except, i know this is going to sound quite strange, but a buzzing kind of feeling around my anus about 2 weeks ago, and went on for an hour or two.

I'm 16 years old and male and don't have a family history of anything like cancer etc, (well my great granddad died of bowel cancer but that is it). Thank you.
