Sadly, I cannot help you with this as I am single since birth. But having FD might be a little difficult, but at least once you find your partner, you know he or she will accept you wholeheartedly and love you genuinely. It might be hard to find, but at least you can make sure it is genuine and will be longer. Still, maintaining a relationship is more of your actions and behavior and how you interact, communicate, and trust with your partner, not with your FD.
