Bit dramatic, yes? How were your male instincts not at play before? Seems like you have an inferiority complex like a lot of gay dudes. Curiosity is normal. Obsession is not
It's sad how meek society has made gay men. They act like it's such a revolutionary thing for a dick to like pussy. They go into these tangents about sexual fluidity when it's nothing more than sensation/pleasure, not attraction/love. They have more built up angst about it than bicurious straight men. It's not that serious. I think this is why bisexuality gets a bad rap, the bicurious dramatize it too much.
