A bisexual teenager describes his life, day after day. He has no girlfriend or boyfriend and finds his life a bit boring thus. One day, he says : "I’m having some straight time with my mates." and right after this, we see him with a group of male teenagers, talking about girls. I would like an English-speaker's point of view : do you think "straight" here means "heterosexual" or does it just mean he does nothing really exciting but hang with his friends? Merci et bon week-end !
