I also feel some explanation is missing. Or maybe an earlier bit of story intro into the universe.

from what i understand, people with the disease wont have symptoms unless someone falls in love with them. if u have the disease and someone falls in love with u, u start to emit pheromones

The one who get this symptons will get aroused easily when someone desired him, or fallen to him. Maybe a potensial to be more maso ...? Idk more
