Imagine you have a pimple.
Now, imagine it's huge and sensitive; so sensitive that if even your clothes brush against it, it hurts
like a motherfucker. (If you actually hit it against something, nobody will blame you for screaming, swearing, and/or crying.)
Next,
imagine that it takes several days of constantly attacking it before it finally stops hurting and starts to shrink. Also, you have to wait until it becomes vulnerable and occasionally take breaks even then.
Then,
imagine that it can and will appear only in places where it's easy to aggravate. If one appear in your groin area, or - even better (not) - ON YOUR PRIVATES, buckle up, because it's gonna be miserable.
Next, imagine that when it's finally on the way out, it may still take another week to fully disappear. And even then, there's a good chance that more will show up unless you do take action.
And just like that, you have a boil. Fun, isn't it? (No, it's not.)
