Whippedcream,
I too have attended a couple of clubs in the past several months (actually one was a play party of about 70 people). Both of which were established sponsored events.
I am in the same boat of young and nubile as you put it, and was approached by several men. What worked for me is that I attended with my Master, and while he would let others play with me a little bit, he was always right there monitoring the situation.
Yes, it was very exciting playing with complete strangers. However the best part of the evenings was speaking to the much more experienced Doms and subs to really get a better education. Both my Master and I learned a lot!
Maybe your best bet is to attend these events with someone you know and trust, and if you want to play with a stranger, insist that your "friend" is either part of the scene, or stays close by.
Have fun, and be safe!
