that wasn't the point. it's a dude dating a girl. their sexuality doesn't change the fact it's a straight couple. a trans man dating a trans woman is still a straight couple. a bi man and a pan woman is still a straight couple. just like a gay man and a bi man is still a gay couple. the term is being used to refer to the type of couple, not the sexuality of the people. as in, a straight couple is a couple of people of the opposite gender, a gay couple is a couple of people of the same gender
