If you are adventurous and lovee doing it with other people then a four. If you like having a small number of people when doing it then a three.
In my experience, foursomes just turn into 2 couples, so if you want something more unusual, go for an odd number. One way or another, the odd man/woman will find a way in.
Although used much less frequently than twosome, threesome, or foursome, a tensome (ten-some) is a group of ten people or things in a single place or use.
A team.
It depends on the people involved. Most men would rather have a two women 1 man threesome. Most heterosexual males just do not like the competition from another male. Women are a little different. It would also depend on if you had had a threesome before. If not it would likely be a huge turn on and would therefore be better than sex.
