My post is probably not going to help, but I just wanted to comment here. There seems to be somewhat of a double standard going on here. It just seems like it were a male stating his GF wasn't giving him enough sex, people would be quick to roll their eyes.

Honestly, if sex once every 5 days was insufficient accord to a girl, I'd feel a lot like the guy OP describes. I'd be turned off, feel pressured, used, etc. Especially if she started bringing up how I was inadequate all of the time. I just couldn't be with a girl who fiends for it as much a guys are often stereotyped to, nor do I have any interest in porn-like sex. Something to consider as a reality, not all guys are exactly the same when it comes to sex no matter how many times the media tries to drill that in. There's not just a switch you can find to just flip and make someone into your ideal sexual partner.

Sorry if I sound a bit bitter or unhelpful here, but this is a really big source of anxiety for me in terms of relationships. Of all of the women out there who complain about men and unrealistic expectations, well what about us guys who feel the same way about some women?
