i'm into women and tgirls and don't view tgirls as men so i don't call it bisexual and i don't know how it can be called bisexual unless viewing them as men...what kind of sex somone enjoys with a person has nothing to do with bisexuality in my opinion. and i don't know what some mean by "straight" because the kind of sexuality i think it means no lifeform on this planet can be said to have. but if someone asks if i'm straight i might say yes because otherwise he/she might think i'd have sex with a dude.
