Men in the Arab world are already porn consumers and have been for decades. I hitchhiked around Egypt for a few weeks in 2009, and men would occasionally show off short porn vids on their Nokias or iPods. Internet cafes in the whole region would, upon request, give customers the details for connecting to a proxy to access forbidden content.
Fast forward to now, and the big porn video sites have content expressly tailored to the Arab world. Everyone has smartphones, and everybody finds some alone time to wank.
