Chandler watches Shark Porn!

but I guess I could become only attracted to annimals if I wanked to horse porn enough yes, and then i would be an actual "pervert" which if you look up the definition of sexual perversions it says that if you fantisise about this stuff enough then thats all that will turn you on from now on, and if that causes social distress then you are a pervert.

Do you have any reliable sources to support this? Include in your sources a legal or medical definition of 'pervert'.
