Trying to schedule a mixed doubles round robin (6 males & 6 females) where:
1) each female is teamed with each male once (6 matches) and
2) each female plays against each male player no more than once.

Is this possible?  I realize each female will paly against one other female a second time.

It is possible to have a tournament like this, however I don't believe that it is possible to schedule it so that there are 6 rounds, each with 3 matches played simultaneously.  The best solution I am aware of is to play 9 rounds of 2 matches as follows:

    Court 1         Court 2          Byes
(M1 F2 v M6 F3) (M2 F1 v M4 F4)  (M3 M5 F5 F6)
(M3 F4 v M5 F3) (M4 F6 v M6 F5)  (M1 M2 F1 F2)
(M1 F6 v M3 F1) (M2 F5 v M5 F2)  (M4 M6 F3 F4)
(M3 F5 v M6 F4) (M4 F3 v M5 F6)  (M1 M2 F1 F2)
(M1 F5 v M2 F6) (M5 F1 v M6 F2)  (M3 M4 F3 F4)
(M1 F3 v M2 F4) (M3 F2 v M4 F1)  (M5 M6 F5 F6)
(M1 F4 v M4 F2) (M2 F3 v M6 F1)  (M3 M5 F5 F6)
(M1 F1 v M5 F5) (M2 F2 v M3 F6)  (M4 M6 F3 F4)
(M3 F3 v M4 F5) (M5 F4 v M6 F6)  (M1 M2 F1 F2)


The repeated same sex opposition pairs are M1M2, M3M4, M5M6, F1F2, F3F4 & F5F6.

Hope that helps.
