Why is it okay that I'm bi but not my bf?

I've been with my boyfriend for 4 yrs now. We're both bisexual. What annoys me is when I tell a new friend or something that I'm bi it's cool, but when I tell people that my bf is, they always say "uhh, okay," or "too much info." Anybody else deal with idiots like that? And why do people react that way? Seriously... I'm jus ranting
