For sure Baraq is bisexual. There have been numerous corroborated stories about him with at least 4 different men, including Kal Penn of the Harold and Kumar movies. But he’s probably the biological dad of his girls so we can’t truly call him gay.
WAIT...what if the daughters were concieved by invitro? Who would say the Pres had sex for sure with a woman then? I can’t see them having actual sex, sorry.
