Just fine and like they said make sure your play partners are safe. When you get tired of it you may want to move, and that is ok too.
The unfortunate thing about this whole thing is, it may be mutual desires with everyone concerned but people have a way of spreading crap around about the other person involved that could ruin someones life. Also, check your motives. Are you doing this just because it feels good or do you have low self-esteem? Make sure your head is in the right place.

think about this, what if one day you find a nice guy that you want to spend your life with, how will you explain to him that you have had sex with numerious guys at the same time, in other words how can you tell him that you have been gang banged on more than one occasion, wouldnt it be weird, i think it would, but damn that shit sound funnn!! have funn but think about your future a llitle. god damn that sounds good
i'd say its unanimous. stay safe and enjoy. oh and stay in charge of your life. you're better suited to know whats best for you anyway. rock on.....
if you find the right person they shoudlnt care about the past. i personally dont care what my wife did before me.
Lucky you!! Just indulge! You only live once so you may as well live it up! If or when you tire of it, just stop. You're in control, after all. It's your world!
