Hi, this was one of the best pieces of advice I ever got from a friend on being pan vs bi vs omni, so I wanted to share it with people who might need it. If you're trying to figure out your sexuality, think of it like this:
-BISEXUAL people might feel an 'ooh' towards boys, an 'ahh' towards girls, an 'ayy' towards enbies, etc. They might feel an 'OOH' towards girls and just an 'ah/ay' towards other genders as well as the individual they're attracted too, because many bisexual people have a preference.
-PANSEXUAL (that's me) people might feel an 'ooh' towards all people. Whether they're male, female, enby, or anywhere around, they feel the 'ooh' if they're attracted to them. The 'ooh' does not get louder 'OOH' or softer 'oh' depending on gender, just the specific person.
-OMNISEXUAL people might feel an 'ooh' towards everyone, like pansexual. However, they feel different volumes of 'ooh depending on gender. For example, they might feel an 'OOH' towards enby people and an 'oh' towards girls/boys/etc
Therefore,
-BI= 'OOH' 'ah' 'ayy'
-PAN= 'Ooh'
-OMNI= 'OOH' 'oh' 'ooh'
I hope that helped because it definitely helped me! Please comment if you have any other questions and remember: You are valid. You are enough. You are loved. Whether you've figured yourself out yet... or not!
