Same i sparred my first ever lesson, to get a feel of my skill level. A good thing to remember when sparring, is the situations, what punches your opponent hits you with, snapping your jab, all the little bits. Of course its natural to throw everything out of the window, you will get hit of course and may not be used to this. But the best advice i can give you is to slow down and keep your hands up. Also go through the old posts on 'Ask the Trainer' there is ample information on the little things that make a good boxer
