"per·vert
Noun:
A person whose sexual behavior is regarded as abnormal and unacceptable."
Although what you are doing may not be considered "normal," I don't think it is completely unacceptable. And even if it was, as long as you are not harming anyone and keeping your kinks to yourself or within a consensual setting, you should be good.
There's nothing wrong with being a pervert, I am and I'm proud of my kinks.
