I believe there are times where there is some turn on to roughness, been there done it, no bruising. There are also specific patterns to bruises which are indicative of trauma patterns. This varies from martial arts, this is a medical approach which specific forces are present which result patterns of physical damage. When a person gets off from this there is something which is causing the self-destructive behavior. I know the force required to hold my wrists down and if I was to struggle, I know the degree of force required to produce finger print bruises v. a bruise strictly from accidentally breaking a vein or capillary. It's much like looking at kids when their parents grab their upper arm and they are left with finger print bruises.

When someone has enjoyment from being bruised, there is tissue damage, and why would this be a turn on? There more happening here then just some simple goofing off. As I said, there are many reasons. Would you not think it odd if your g/f said "I love it when I have bruises around my wrist from being restrained?".

Enjoying rough sex is one thing, physical damage enjoyment is another. Try your own wrist, see the degree of force required to bruise yourself. Put your one hand around, and give it a shot.

There is a whole host of very unusual things people do for enjoyment, many of these things boarder on self-mutilation (or are) or allow for self-destructive behavior. The psych doc figures it out.
