What do you think about Bisexual relation?

I watched Tyra Banks show about Gay Kingdom episode which is in the Kingdom the bisexsual guy were banned.. no offense to Bisexsual but i am agree. if i had bisexual boyfriend, iam afraid he would not stay for long, because i assume every bisexual would have family with a woman. so there is bisexual guy close to me, and i am confused what to do?
