Katoptronophilia is the (relatively common) paraphilia for mirrors.
Katoptronophiles may enjoy stripping in front of mirrors, sex in front of mirrors, masturbating in front of mirrors... basically anything in front of mirrors that constitutes erotic activity.
Ne-Yo outs himself as a katoptronophile in his romantic song 'Mirror'.
I must be honest with you babe (just gotta be honest babe)
I love to watch the faces that you make (when we make love ooo wee)
But when I'm behind you holding your hips and you close your eyes and bite your lips
I can't see you so might I suggest a change
Now mama please don't think me strange for what I'm about to say
(please don't think me strange)
If you know anything bout me by now
you know I'm a freak just follow my lead
Baby I love making love in front of the mirror (in front of the mirror)
So that I can watch you enjoying me (baby tonight)
Baby tonight let's try in front of the mirror (in front of the mirror)
Watching ourselves make love
Girl why don't we
Can we make love in front of the mirror
