I don't watch all that much straight porn because most of the time the cameraman is focusing on the female and the poor guy doesn't get much of a look-in. However, this "Best Sex Positions" site does have quite a few scenes where the guy is mostly on view and one of the best is entitled "First Posture of the Perfumed Garden." Like most of the other guys used in these scenes, including James Deen, he's a professional porn star but I forget his name. (He's in the first 3 screen shots below). You also get some big dicks and nice male butt shots as well as cum shots. I found it best to turn the sound down, as we often get the usual squealing from the women - enough to alarm the neighbours - or an overlaid commentary explaining what to do. Anyway here's the link so feel free to browse! ...
