okay so about a month ago i was rubbin one out when i noticed a purple bump the size of a peice of corn on the side of my balls. i gasped and finished jakin off. when i took a second look at it i thought it was a pimple so i tried to sqweeze it and it hurt like hell......it was really solid to. ive been trying to ignore it but it wont go away.im still wondering if it is cancerous. anyone else with the same problem?
