Let's start with the easiest misunderstanding of being bisexual: Stereotypically, people assume that bisexual men are softening the blow that leads to 'accepting' the reality that you're a gay man.
If only it were that easy; bisexuality is not a binary journey in a vessel to binary homosexuality. I'm still attracted to women and had a child with one.
While, validly, there are often gay men who sometimes embrace a bisexual front before segueing into exclusive homosexuality on the journey of self-discovery.
