You have to tell you future partner. I really dont think that will be a problem. I have hid it only from society. I know its hard. I think being a man makes it harder. I was always worried about driving and work. I wanted to be part of society in a normal way. People like to talk and i wanted to be out of their talk. My advice is tell your life partner. You have no choice. Everybody in time will have some medical condition. Time goes by anyway.
