There is no such thing as 100% straight porn
Heterosexual porn is 50% gay because there’s a man in it
Futanari porn is 25% gay because it’s a girl with a dick fucking another girl
So going by that logic the answer is lesbian porn right? Ha, no
Lesbian porn is actually 100% gay because there’s two people of the same sex fucking therefore there is no such thing as 100% straight porn all porn is actually just a little gay thank you for coming to my ted talk
