Finger guns are a huge part of bi culture. 👉😎👉

You might get a kick out of this, could bring a little life to your Bible study. http://www.wouldjesusdiscriminate.org/

Memes and online culture count. Just like writing counted as culture when that tech emerged. There is an online bi culture, ime. It’s laid-back, self-aware, and flexible. And it sits in chairs like Riker from Star Trek: TNG.

But “affirming your bisexuality” is different for everyone. Due to gender norms, women wearing bi pride flag colors are less likely to be assumed to be queer, as misogyny means “feminine colors” like pink/purple on women fly under the radar, so if your gender presentation is female, that might be one way to express yourself. But if you’re in the closet and affirming your sexuality to yourself, what I would think would matter would be art and community. Join some bi groups online anonymously if it’s safe for you to do so. Particularly bi + a shared interest groups. And take in some media that treats bisexuality as “normal” if that’s safe. Here’s a good place to start: https://en.m.wikipedia.org/wiki/Media_portrayals_of_bisexuality

Never forget that you are wonderful and worthy exactly as you are.

Bi here! I have a small rainbow eevee pin on my backpack for fun (plus, it's a cute pin).

As for culture, there are some memes, but really IRL, I haven't seen much, as everyone kinda just goes with the flow. And honestly, I'm okay with that. Most of my friends are bi+ or sone form of queer. There's not really a prevailing culture at gay bars here either, which is kinda nice. Everyone just comes as they are, whether they are old or young, and you would be hard pressed to label them because they don't look "gay/bi".

I think to some extent, it's good when we get integrated into society and become a part of it. We used to exclude German Americans, but now they are impossible to distinguish from the rest of society, as they became normalized. Same with LGBT, to some extent, even if there's occasional retrograde motion here or there. If you want a good book to read, check out "The Lavender Scare: the cold War persecution of gays and lesbians within the federal goverment" by David K Johnson.

It allows you to see how recursive history is, particularly on gender rights, but also just how far we've come within people's lifetimes :)

There's definitely a lot of meme culture, but I disagree with the idea that there isn't a distinct bisexual culture. It's been around for a long time, it just often gets erased via assimilation or discounted so it's a little bit harder to find.

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 :)

Tumblr?

[It’s a joke, but also… is it?]

Meme wise? Garlic bread, frogs, and sitting in chairs the wrong way.

Real world culture? Maybe watching some David Bowie documentaries, he might be the most famous bisexual that I know of. But he's also not the definition of what bisexual is. It's more of a spectrum in and of itself, as it manifests differently for each individual. Like for me, I'm bisexual but in a monogamous relationship which would not work for other bisexuals and that's okay. Explore yourself to find what bisexuality means to you.

Real talk, meditation helped me discover myself and what my gender/sexuality meant to me. Just being with myself, my inner thoughts, and listening. I know that meditation doesn't necessarily work for everyone though, so you may need to find another way to explore yourself. But that's what worked for me so just sharing my method.

I wish you luck in your journey of self discovery, happy to help where I can even if our journeys aren't identical 😊
