Oh, fuck. If I know I like men and women, how do I decide who to settle down with in the end?
I know this question is just an expression of your immaturity, but it annoys the shit out of me when people frame bisexuality as a false dilemma between genders. It’s not.
Go fall in love. Go get your heart broken, and then go do it again. Find out what it takes to be in a long-term relationship regardless of either of your genders. Learn about yourself. Figure out the kind of person you want to be and the kind of life you want to live.
Go do all that shit, and when you’ve finally grown up a bit, when you’ve wrapped your head around the wonderfully messy and messed-up complexity of interpersonal relationships, when you’ve come to terms with how little control you actually have over your romantic destiny in the first place, maybe then you’ll realize how ridiculous it is to reduce major life decisions about potential life partners to something as ultimately inconsequential as “penis vs vagina.”
