Are we innately bisexual?

Sigmund Freud says yes. Poetry says yes.

And sometimes I ... feel yes. And according to Wiki (aahh good ol'):

Innate bisexuality (or predisposition to bisexuality) is a term introduced by Sigmund Freud (based on work by his associate Wilhelm Fliess), that expounds all humans are born bisexual but through psychological development (which includes both external and internal factors) become monosexual while the bisexuality remains in a latent state.

I find myself asking in times of deep uncertainty, when do I wake up from all this?
