kremmm: when does a sexual traunt become an orgy? In sex, an orgy is a sexual activity in which four or more participants are present and involved in sexual activity with each other. Group sex is sometimes referred to as a gang bang, though this term is used by some to mean intercourse between one woman, or one man, and a group of men, one after another. An alternate slang phrase for this practice is "pulling a train" Practical difficulties – but which also contribute to the enjoyment – in participating in an orgy include figuring out where all the arms and legs go, figuring out what positions work and in what complexity, and addressing in advance such issues as consent and jealousy. - - - - A "drunken orgy" resulting from intoxication may leave the participants embarrassed and upset in the morning when the hangover strikes.
