Change happening every now and then?

I was thinking of a story of temporary sex change--see my other post. A boy/adult men visits his uncle/a distant relative. One thing leads to another and he wants/or is told to become a girl with female body parts. Yet he doesn't want to to miss his life back home. They search around and find a doctor/surgeon who can perform surgical changes that are not permanent. At the end of the stay, the boy is reverted back to his male parts and returns home. Then ever summer he heads back to his uncle/relative and gets changed into a girl until he makes his decision which life he wants to live.

I know from research medical operations cannot create temporary sex change but what do you think of this plot? I go this idea after reading the stories "A Life Ever Changing" and "I can't go home like this.".
