There must be no discussions like this on the GD board. It comes up a lot on this board. Search the message board for "newbie" or "first timer"

First of all, good luck and have a great time.

The question you pose is difficult to answer not knowing what you are in to (top/bottom/oral or all), but I am posting a thread link to the last question like this related to getting "topped".

Don't be nervous!
