I don't know what I consider to be the right answer. Maybe 5, definitely not less. So I voted 5. Threesomes and foursomes are group sex, but to me it doesn't feel right to call them an orgy.

I don't think the gender(s) or orientation(s) matter.

I've heard the term fourgy, but nothing that alludes to anything higher than that - so 5+ I vote is an orgy.
