purple boil on penis

hello, i am a 14 year old boy.
years ago i found these tiny white spots all over my penis and scrotum.
however i have found that these are natural for a boy of my age.
a day ago i found a huge red spot with a tip on my penis.
as soon as i got home from school i told my mom.
she told me that the best thing to do would soak it and pop it?
so i did that
now when i woke up this morning i found the spot had turned into some type of boil thing
it looks red and has a black dot in it.
i popped it again this morning and a bit of blood came out.
any ideas what it could be? or what i could do to make it go away?
btw i have only had oral sex and that was like 5 months ago.
please help im really worried about this
thank you.
