Swingers parties...

hey, Im new on the site and am a very sexually minded 20yo(most of us are) its a young penis thing:P:P Anywhoo.. I have been recently thinking of going to one of the swingers parties down at burswood but im left kind of in the cold to well "ediquite" and rules i guess. I know the whole no means no things is a hard and fast but could i get some advice (being that i am single and young, which apparently dosen't go in my favour =p) about what i can expect or prehaps maybe some previos experinces/ Unwritten Do's/Dont's of this semingly fun activity? I am little shy and what now but i would like to get out the and experince it at least once in my life.
