As a lot of people have said. Who you are as a whole is what will build a relationship that lasts. Dont start with diapers but dont hide it either. My girl and i talked about things for months before she new i used diapers. Wile our relationship started out mostly long distance so not reveling diapers was quite easy still when it came out we already cared a lot about each other. If diapers are a need or just for fun the rest of life is what will make or break the relationship. If diapers end it there was not much there to begin with imo.
