Is it normal i tie shirts around my face and masturbate to my reflection?

This is a guilty pleasure of mine and I feel disgusting even just typing this now, but for years now I've had a habit of tying shirts around my face like a ninja mask and masturbating to my reflection. I've considered taking my paraphilia further and buying surgical gloves and assorted utensils to further enhance my arousal, but I don't want to feed my bizarre habits. I always feel iffy while I'm doing it and prior to climaxing I feel downright repellant, but it gets me off like 'whoa' and 'damn'. I also sometimes fantasize about raping gay men when I do this, even though I'm mostly heterosexual.
