I haven't been water skiing but its definately something I'd like to try at some point or another.
I've been knee-boarding, where they pull you on the board behind the speedboat. I managed to get up on my third or fourth try and by that time I had a big scratch up my arm from falling on a load of shells in the shallow water, got into the middle of the river and then took a spill, head-first straight over the front of the board.
I went skiing once too... Only managed to get down the slope without falling over once, hehe, one time I ended up with one of my skiis half-way up the slope and myself lying at the bottom (ain't it great that some of the more experienced skiiers are willing to bring your skii down for you?)
Anyways, glad to hear you had fun and congrats on getting up on your second try
Make sure you keep putting sun-screen, aloe vera or moisturiser where you got burnt too to minimise the effects like skin-peeling.
