Can porn make you engage in sex you don't want?

There is a great talk on TED which describes the problems men are having who watch too much porn. Close to the end Wilson addresses how porn can sway you away from your sexual orientation toward sexual behaviors with whatever sex you are not attracted to.

Again this facilitates the dialogue I am trying to have here on this blog which is that straight men can have sex with other men. It is about behavior, not sexual orientation.

This is true for gay men as well as we see everyday in which they are having sex with women even though their orientation is homosexual.

The movie Shame http://www.amazon.com/Shame-Blu-ray-DVD-Digital-Copy/dp/B006OB3K56 showed also how a sexually addicted man escalated his sexual acting out behaviors to the point where he had sex with men even though he was heterosexual. It was accessibility, not sexual orientation.
