It is rather interesting where lines of similarity can be drawn between two seemingly different things that at first glance may appear to have virtually nothing in common and yet almost everything has a commonality somewhere along the line.
For over a decade I have practiced various martial arts. Among the styles was jujitsu. (Most know of the art and I have a feeling there are more than a few practitioners in here as well, so I don’t think I’ll have to explain it ?). Being able to contort and grapple and manipulate the human body while nearly being controlled yourself is an art all of if it’s own. Jujitsu focuses the mind and body on how best to use the body’s joints and limbs to bend and twist a person to the near limit without inflicting long lasting harm. It is a powerful and effective art. I began using jujitsu in my bdsm lifestyle. I learned how far the body can bend before pain can result in injury. I learned great arm and leg locks that can be converted into rope tying positions. In my aspect of BDSM which teeters around mid-core sadism and masochism; the pain inflicted upon the body I learned where pleasure and pain mix. How I can inflict pain that causes pleasure. I learned it was a very fine line but I found great pleasure in walking that line...and even greater pleasure in experiencing my submissive’s pleasure. When in combat I felt a heart pounding joy and pleasure and in fact it was not completely unlike the pleasure of inflicting pain during bdsm. It’s a fine line but when walked, you can see the commonalities between martial arts and bdsm...between combat and sex.
