My advice, keep both the male and female separate in their own tanks. Bearded dragons are very happy alone and with interaction with their owners. Most quality breeders and dragon owners keep their dragons separate at all times, only introducing males and females for the short time needed to breed them. It only takes one or two matings to ensure enough fertile eggs for several clutches in that breeding season since dragons can and do retain sperm.
Your earlier post indicates your female is only 8 months old. She's too young to have babies. 18 months or more is often recommended as the minimal age before breeding females, however some breeders do and have great success breeding females at 14 months of age. As you can see, 8 months is still too young, by all breeder standards.
Interactions between two dragons may be neat to watch. However if that sort of socialization is what you want to see more than ensuring the dragons are healthy in their own enclosures, bearded dragons are not really for you. Get a pair of guinea pigs instead. They have much more social interactions with eachother and their owners than bearded dragons.
Wanting to trade or sell your male just so you can get another female to house with your current female, certainly implies you don't really like or appreciate the dragon you have now. Maybe you should just get rid of both and get a dog for the family to play with. Owning a pet, any pet is a responsibility that is more than just ensuring you are entertained, you alone are in charge of that creature's livelyhood. He/she depends on your for it's survival.
Another thing to consider about having a male and female bearded dragon together to breed, is the cost of taking care of the young. Bearded dragon females can have as much as 100 eggs in a season, spread over several clutches. That's a 100 more mouths to feed upon hatching. Raising 100 baby dragons to an age old enough to find new homes costs alot of money, in the $1000s. Egg laying is also very stressful for female dragons which means to ensure they are healthy, extra supplimentation and food. Then their is incubation of the eggs, feeding and rearing of the young and finding them new homes. It adds up fast. If you are just planing on killing any eggs she lays, they it would be better and cheaper in the long run, to just house them separately right from the start.
