{NSFW} Have you ever had a threesome, foursome "moresome"?

This question and it’s responses got me curious. If so, did you enjoy it? Would you do it again?

I’m guilty of all the above, I was very young and had a great time. I wouldn’t do it now though because I don’t have the self confidence to get naked in front of that many people at one time anymore. Oh and the extreme fear I have of contracting an STD or something Comet wont get off.
