Some would say all you need is to cuff your jeans and appreciate lemon bars! Jokes aside, I always took the prevalence of memes like that by and for bi people as a self aware dig at the fact we don’t really have much of an established culture just yet and it’s kind of an ongoing thing. That’s been my interpretation at least, I’m certainly no authority.
At any rate, hang in there and I hope you manage to find your way out of the closet and into a situation you’re comfortable with soon if that’s your wish :)
