Legion. I have a V.
here goes explaining:
I am married to and in love with Maca
I am also in love with GreenGecko
Green and maca are friends-NOT lovers and never will be as they are both straight men.
Could be men or women in any role but it's a positioning where there is one person who is in love with two who are not in lovewith each other.
If all three were in lovewith all 3 that would be a triad.
"Love As Thou Wilt"
