Gaspard and Jo have been together for 2 years, they are in their mid 20s and live in Brussels. Jo (a heterosexual woman) has always known that Gaspard considers himself bisexual, even though he has never had sex with a man. Their relationship is fulfilling, happy, supportive and built on a solid trust. Gaspard has a soft, feminine side that Jo likes very much but is sometimes teased or questioned by people around them. Jo does not mind, she knows who Gaspard is and she likes his different sides. There is a lot of respect between them, and no predefined ‘roles’. One day, however, Jo notices that Gaspard is troubled by a man. They talk about it, and Gaspard finally admits that he has never had a relationship with another man. Jo, confident in their relationship, urges him to try it. They decide together that Gaspard will take the plunge, which he does. A disturbing experience: he discovers another sexuality, which he considers different from the one he has with Jo, a more animal, more instinctive sexuality, even if this first time is mixed with a feeling of shame. Gaspard has enjoyed himself with the man he met and soon feels the need to do it again. Jo, on the other hand, begins to feel bad about the situation. Together, they try to figure out how to make their relationship work.
