Bondage? Barefoot! I'm a big "if the damsel isn't barefoot, she isn't in bondage, she's just... tied up" guy. Other than that, I prefer pics that show the whole damsel, rather than close-ups or medium shots that crop off bits & pieces. Also other than that, I like "comfy" bondage - please hold the pain, welts, cuts, bruises, and blood. Also no drool (ick!). Gags are optional.
You?
