When your boner turns into a screaming pain monster after you finger yourself until your hands fall off or you get a boner so long it feels like your pants are about to explode.
After watching 10 hours of anime and fapping nonstop, I got a painful boner so bad I thought my leg was on fire.
My boner was so painful I screamed in the middle of class and got sent to the principal's office.
I had a boner so long it looked like I was trying to breakdance with my pants.
