Stop fetishizing bisexuality.
Stop thinking that just because you can hook up with a member of the same sex, you're bisexual.
You're not. You could be bi-curious, but if you're not willing to marry someone with the same genitals as you (not just hook up with them) it's not the same thing.
Stop always being nasty when seeing 2 guys or 2 girls out minding their own business.
If they're holding hands walking down the street, don't turn to your friends and say you wish you could see them do that thing you saw on PornHub. Not cool.
Stop claiming yourself as bisexual if you have a one night stand. It's not the same thing.
You're spreading misinformation and lying to yourself.
Stop putting down people who are bi-curious!
If a man or woman has a "different" sex life or are experimenting and you know about it, you have probably been entrusted some sensitive information. Society likes everyone to have everything labeled especially with relationships. But human sexuality is fluid, and it can be hard to put words to things, especially if it's a new interest. Experimenting doesn't mean your bisexual or even bi-curious.
Words matter.
And labeling yourself as something you're not is hurting society's movement towards open-mindedness for all.
