The visuals are just a jumping off point for me. I cant just stare at some dude's bod and whack it. I might start weaving a fantasy around him and imagine what we might end up doing, but it all internal imagery.
And if I do look at porn, which is extremely rare, the super close ups of a cock plunging in and out of some chick's junk definitely doesnt turn me on. You can tell those things are shot by guys, for guys. There would be more women watching porn if more porn were made for them.
