You accidentally pissed of a wizard or something, and in retaliation you've been cursed so that every time your penis gets erect while your wearing any form of pants, your cock and balls keep on growing until they burst free from their cloth imprisonment. The only way the curse doesn't take effect is if theirs no fabric, cloth, or any type of containment touching your genitals. When your penis goes flaccid your genitals go back to normal.

How do you react to this?
How does this impact your life?
