Is it normal to get extremely aroused by looking at my naked reflection?

I get home from a long bike ride or a really deep yoga practice. And when I see myself in the mirror, I peel my clothes off slowly, like a strip-tease, to reveal my naked self, and I get extremely aroused looking at "him" in the mirror. Every thing, from the look in my eyes to the contours of my legs, to the hollow of my smooth belly makes me hungry with self-desire.
