I no longer Christian but I had a Christian upbringing although it wasn't a very strict one, and I certainly remember that premarital sex was frowned upon but I don't remember anything about anyone saying masturbation was off-limits.
I tend to look at it like this. If you're Christian you believe that God was a creator. If he created people to be horny whether they were married or not, then if you really believe he was the architect of man, then that would suggest he doesn't care what you did about that.. I figure if he was really a stickler for no masturbation, the heat of created people to only get horny after they were married and only for their spouse. Which is nowhere close to reality.
