Hey Sherwood, I see you are 50/50 in terms of orientation, as I am. Not that it is easy to put a percentage on it. I have days when I feel 99% straight, and crave a woman, and other days when I am at the other end, guy-fixated. This is usually after seeing/meeting someone I fancy. Whatever, a boner cannot lie! The whole question of gay/bi/straight mystifies me, which is why I posed the question of whether a 100% "straight" guy is sexually aroused by the sight of his own cock in the mirror to the point where he gets an erection and the urge to masturbate.
I see the urge to masturbate in a mirror, or to take pics and vids while jerking off, as some kind of image reinforcement device that serves to augment one's sense of sexual attractiveness. There is also a performance element in it, the "showing off", the acting out. This requires a degree of objectivity about the image reflected back in the mirror - "Oh yeah, that's a hunky handsome guy with a big dick there! And look at what he's dong with his dick!. He really knows how to use that thing, to really pleasure himself. Fuck, that looks hot!" etc etc. Gay/bi guys have that objectivity because they are aroused by the sight of male bodies/cocks in general but, presumably, "straight" guys do not possess that mechanism?
Perhaps they are turned on by the anticipation of the pleasure they know they are going to get from playing with their cocks, rather than by the visual stimulus. Please forgive my ramblings - male sexuality has so many shades and aspects to it, just when you think you have pinned it down, it somehow evades you.
