As Edward left the room, he muttered "I wish you knew what it was like to have something of the opposite sex." It wasn't easy for Edward, living his life with female breasts. He just wished his wife was a little more understanding.
The moment he made the wish, his wife was entering the bathroom. After lifting up the toilet lid, she unzipped her pants and pulled out her penis.
She didn't hear Edward's wish, so she thought it was normal for her to have the male sex organ.
