I was satisfied enough, insofar as it was possible for my young, horny self to be satisfied.Hope you felt satisfied in the end
Group sex can be incredibly cathartic in that you just get to let loose without feeling wrong - that's the main appeal of it to me, at least. Word of advice though: always set ground rules, make sure you can trust the participants, and never go into one without an ample stock of condoms.I feels jealous of you @Shivorah..I always gets curious about gangbang and 3somes. Never dared to fulfill any such desires.
Actually organising a gangbang can be a bear of a task, though. In Europe and to a lesser degree America, swingers' groups and parties abound (I've been to a couple organised by prominent porn actresses), though expect to find these only in bigger cities. I can't account for India, but generally speaking, if you know where to look for something, you'll find it.
It's much easier to assemble a threesome - look through (or put out) personal ads, or ask a couple of friends if they're interested. If you have a partner, it's even easier: you only need to fish up one extra friend. That being said, I would advise talking to your SO beforehand.
Hopefully all of that helps!
