I don't know how you interpret this as "a mere depiction of gay characters."
The given quote in the video you linked to was:
"Excited now, he pushed into her, and she squeezed her eyes as tightly as she could, her tongue circling her lips. He pushed harder, his breath heavy and labored. She scratched his back, and he cried out. She bit his ear and pulled his hair."
This is a description of what appears to be heterosexual characters. Nor does it appear to be a "mere depiction". I would reserve that for something like "Heather Has Two Mommies" (a mere description of a homosexual couple) or "Mr. and Mrs. Brown" (a mere description of a heterosexual couple who have befriended a bear from darkest Peru).
