I can understand what you are saying Matt, my first sparring session was in full contact kickboxing and I remember both me and my opponent were very nervous. ( he threw up at the end of the round) but I remember getting winded really quick ( I still smoked then) and at one point when he was backing up, he threw a roundhouse kick that hit me square in the nose and I started bleeding like hell. At the end of the first round I was bloody, exhausted, sucking wind, and yep, I felt like a train wreck.
