not sure how i feel..

so first of all, i think i am definitely heterosexual.. but sometimes when I get high and sit down to, umm, you know.. i get the urge to watch porn with more guys in it, sometimes i even watch straightup gay porn.. but as soon as i finish, the feeling goes away, like it was just some weird sensation that i shouldn't have.. you know how that can happen, haha. anyway, when i'm sober, i usually never have any thoughts that would make me identify as gay, so I don't really know how to feel.. can anybody relate or explain? thanks :)
