At least from the outside looking in, it seems like girls and women are under more pressure now to imitate what guys see in pornography, which is horrifying in and of itself.

That's my sense as well, and I agree, it's horrifying.

I can imagine how being constantly subjected to this expectation from men, a woman might get the impression that objectification is an integral part of heterosexual relationships.

Yeahh.. it's so sad. Like you said, I also sometimes feel grateful, because of things like this, that I'm gay.
