First.. Exasperated sigh.

Second.

Even some bisexual people don't realize it until later in their lives.

Years and years of people being oppressed or hated for liking their own gender kinda makes that hard or terrifying.

I only recently started exploring my bisexuality, I didn't even think I was bi until I was 27. Didn't do anything with any men until 29. I just turned 30.

Third.. Your text is painful to read.
