Not a single drop

Despite the fact that it had been called a “curse,” Jim was actually quite pleased with what the witch had done to him. Whenever he was splashed with cold water, he’d turn into a female but return to being male by warm water. It wasn’t long before he decided which he preferred. He took ice cold showers each morning and made sure to cover up from head to toe when warm summer rains fell. He didn’t want to risk getting hit by a single drop!
