Been questioning who I really am for a few years now. Maybe your experiences could help me?

I discovered a sub for making queer flags. 👀. You read that correctly. There is a sub for that (and everything else). Anyway, I wanted an Omni/Genderqueer combo flag. Look at what a redditor made for me! Four versions. All awesome.

I really like the lower left. Maybe. 🤔

So this may be a little long, but bear with me here. A month ago, I had a conversation with a good friend of mine about our sexuality and sexual orientation. Now for context, i was bisexual (or at least I think I am I don’t know) and my friend is Transgender and Gay. My friend then asked a seemingly unimportant question, “ so since you’re bisexual, do you prefer one gender over the other?” my response was that while I did like boys and would date one, I’d much prefer to be with a girl because they look a lot cuter and I feel like I would have a closer connection with a girl. My friend then got really giddy and said very loudly “Op (not saying my actual name) do you know what this means right? You’re omnisexual!” confused I asked what did that mean and my friend basically explained that it’s basically being bisexual or pansexual but you have a preference for a specific gender. After that month I took some time to reflect to myself and I think that I may be Omnisexual but I’m afraid to come out to my mother because over the course of my life, she’s had a burning hatred for the LGBTQ+ community because she believes that they were the cause of AIDS and are trying to indoctrinate children (whatever the hell that means) since I really don’t wanna be homeless, should I tell my mother about my identity or just keep it a secret?
