Is it normal to achieve orgasms through my own reflection?

For almost a year now, whenever I'm jacking off, I can only achieve an orgasm if I see myself nude. Whether is through a mirror, cam, pictures, whatever but I have to see myself in some way. Porn doesn't do the trick anymore, and I've been single for a while, however I don't think I'm gay since I haven't found a man attractive (actually the sight of penis disgusts me, aside from my own that is). Although I do find women very pleasing to look at, when I start dating someone I lose my interest rather quickly.
