You, Sir, are exactly right! Anyone who finds those worship sites stigmatizing should find these training videos stigmatizing too. They are the same product targeting the same audience. No one--and I mean no one--buys these videos to get training tips. If you want real training tips you book one or more sessions with a trainer. If you are gay, bi, or "straight with a curve" and want to be titillated then you buy these silly videos. 
Bay I respect you and I actually think you are more astute then a lot of people give you credit for, but you have the tendency to be rather silly.
Are training videos Whack off material for Schomes? I'm sure that this is the case for some people, but I honestly think that the majority of patrons of such things are straight. There is no way to possibly quantify this, but I would make an educated speculation that only about 20-30% of the bodybuilding subculture is gay, or in the closet.
This is a high percentage compared to most subcultures, however it is still the relative minority for ours. I still buy bbing magazines, because from time to time I learn something I didn't know before. Doesn't happen all the time, but it does happen, or sometimes it refreshes my memory about something related to nutrition, pharmacology, biology, etc. Also I like to support this subculture.
That said I don't think in the 14-15 years I have been around BBing I have never once had a sexual fantasy, or thought about any of the men involved in it, and I can say this honesty. Actually I am usually so oblivious to the fact that a bodybuilder is almost naked, as it simply doesn't register to me on any level sexually.
This doesn't mean that all people are like I am....but I know I'm not the only one. I don't watch training videos, (outside of occasionally viewing a youtube link off of getbig), and the reason is not that I think its gay to do so, but that most Training videos are about as exciting as watching late night c-span. Bbing videos are incredibly boring....but I wouldn't automaticlay fault someone for being a Schome for trying to learn something from them.
Honestly I think its more naivety then gay impulses. I think most people that buy those videos think that these pro bodybuilders actually know something that they don't....when in fact they are usually just genetically blessed, and can get away with whatever style of training they want.
Bottom line...I think that insecurity drives more people to bbing then sexual reasons. Most of us, for one reason or another, identify with the astehetics of a powerfull comic book physique, and its the need to overcomensate that drives most of us to try and live into that aesthetic. I don't see this as a failure, as this is no different from anyone else, (we all have insecurities and need a crutch from time to time), but the neat thing is that someone that got serious about bodybuilding is someone that decided to do something about their desires/insecurities, where as most people do not have the passion, or drive to do so. (Regardless of what area they feel weak in.)
