The only time I ever jack off while looking at something is when I'm traveling. I usually pack a few interracial (black on white) BBW DVDs, and that tends to do the trick for me. I do like the thick girls.
Haha, now that I have a webcam, I guess I've stroked off for my viewers a number of times, but that's more for their amusement than mine.
The great majority of the time it's just me, in bed, with a good fantasy. (We have separate bedrooms because I sometimes snore.) I actually think about my wife most of the time, believe it or not. Only I'm thinking about her fucking other guys.
