I'm pretty sure that's the selling point. It's the Best Thing Ever Written because there are no gay people in the universe. No gay people! Marvelous! Stupendous!

She completes her doctorate in an impossibly short period of time, and becomes a professor without any publications. One of her students (Brad Hawkins, top photo) catches her eye, so she marries him. Later they divorce, I think. It's not really clear.
In the final scene, he begins college. His roommate and two girls invite him to go camping for long, boring conversations about the meaning of life.

But it doesn't explain why this is such an aggressively heterosexist world. In Psychology class, the professor lectures on universal heterosexual desire: "Whenever you see someone of the opposite gender, you are instantly drawn to them." Questions of "Do you have a girlfriend?" and advice about how to handle heterosexual relationships inform Mason's life, long before his parents have any way to know his sexual orientation. Once he becomes a teenager, it's girls! girls! girls! all the time.
I think the new Transformers movie is playing in the theater next door. See that instead.
Or anything on the Hallmark Channel. At least it will break up the monotony with commercials.
