What’s wrong with being bisexual?

I’ve had some strictly gay girls turn me down for being bisexual. I’m so confused 🤷🏽‍♀️ I thought it’s LGBBBBBBBBTQ why are some people being an ass about bisexual. 🤔ummm before you become fully gay don’t you start off bisexual? What happened to uplifting, some thinks it’s nasty? This girl stopped being friends with me because she thought I was confused and there’s no such thing as bisexual, that shit hurt my feelings for a long time.

I’m so very sorry that I offended anyone with the statement “you start off that way”. My apologies 😔
