After reading TGTMD, I was wondering where the idea of Andorians having four sexes, and thus needing four members for marriage, started. The first I ever read of this custom/biological scenario was in the DS9 Relaunch, but I was wondering if it had ever been mentioned in any of the series and/or any of the previous books.
Any and all background info would be greatly appreciated!
