Here is a schedule with the all male with all female property you are looking for, but I don't think there is a good way to order the 8 games - however you do it there will be some people who will have to play three times in a row.

[(M4 F2) : (M2 F4)]
[(M4 F1) : (M3 F3)]
[(M1 F4) : (M3 F2)]
[(M2 F3) : (M3 F4)]
[(M2 F1) : (M1 F3)]
[(M4 F4) : (M1 F1)]
[(M4 F3) : (M1 F2)]
[(M3 F1) : (M2 F2)]

I need the same thing, except I would like examples of 8 person through 24 person? same number of males and females, playing with everyone of the opposite sex, and playing each other person at least once?

This is not that easy to schedule as full balance is impossible.  If you had 10 persons, there there are 25 possible mixed sex partnerships, but with 2 partnerships in every match you can never have all partnerships exactly once, so the next possibility is 12 persons, for example:

[(M1 F4):(M5 F6)]
[(M6 F2):(M3 F3)]
[(M4 F5):(M2 F4)]
[(M5 F1):(M6 F3)]
[(M2 F2):(M6 F6)]
[(M3 F5):(M1 F1)]
[(M4 F6):(M5 F3)]
[(M6 F4):(M1 F5)]
[(M2 F1):(M5 F2)]
[(M6 F1):(M4 F4)]
[(M2 F5):(M1 F3)]
[(M3 F2):(M5 F4)]
[(M4 F1):(M1 F6)]
[(M3 F4):(M2 F3)]
[(M5 F5):(M4 F2)]
[(M2 F6):(M3 F1)]
[(M4 F3):(M1 F2)]
[(M6 F5):(M3 F6)]

But note that it is not possible to have everyone play against each other the same number of times, above the three pairs (M1 F2), (M3 M4) & (M5 F5) never oppose each other.  To have a truly balanced schedule, each player has to have one other player with whom they never partner or oppose (see the spouse avoiding schedules here.

I need a format for a mixed doubles volleyball round robin for 14 players (7 men and 7 women)where each man pairs with each women once, and against each other once or as close as you can get. The important thing is that each man and women are paired once together?

Follow the 'schedules here' link above and then add an extra round to the 14 player schedule along the lines of:

[(H1 W1):(H2 W2)] [(H3 W3):(H4 W4)] [(H5 W5):(H6 W6)]

This will not meet your criterion exactly as H7 with not have partnered W7, but all other male female pairs will have partnered once.
