Have you ever worked out so hard that you feel the same as you do after a bdsm session? What would you compare your hardest workouts to? I've ran so hard I got the runners high (which literally felt like one time when I was in the hospital and given morphine). Today I just went so long and hard that when I finished I felt like a sexy puddle of compliance (which reminds me of how I feel after leaving a session with a master Dom).
