I've also been doing Karate for just over 6 months, and gained my 7th kyu in March. I've had to spar from the beginning, against people of equal level and people of higher levels (including my Sensei). Of course, its scary at first, but I just try to go for it - the only way to overcome fear. Of course, if you get hit, it hurts, but you get used to it, and try to learn to block or get out of the way. But the big problem is, being so new, I don't have the techniques or combinations to do it well. I tend to agree that it would be better to start free sparring later on, when some techniques have been learnt sufficiently well to execute quickly and smoothly without conscious pre-thinking. The other problem I have is I regularly have to spar against the biggest guy in our class - I'm 6 ft tall, but he's about 6 ft 2" and weighs about 50 lb more than I do. I spend a lot of the time on the floor!!
