My only comment or question would be about the type of guys you use. I can say that those of us here who have any inkling towards any kind of BDSM thing would run screaming from the room at the sight of a itsy-bitsy-teeny-weenie-twinky like the guys you're using as models.

I mean, they look like children, and there really isn't such a thing as children into bondage.

Or they're rare to say the least.

If you want to do a BDSM thing, I'd suggest using stronger looking guys. I don't think guys that small could subdue a puppy, let alone somebody old enough to be having sex.
