Is it normal that i am hetro but enjoy masturbating to gay/shemale cum swallow?

I like all watching porn, it's one of my most favorite pastimes, and getting wasted on weed, and every now and then i get sooooooooooooo wasted i get off to gay shemale cum swallowing and granny porn, i literally explode and have massive orgasms to that as opposed to watchin m/f straight porn which doesn't feel as 'naughty' maybe cos it's what i done all my life, 'normal' porn and watchin she/gay porn gets me off cos it ain't 'normal' to me. anyway i know i aint gay but i'd like to know if anyone else feels the same.
