If I owned a cool male like a Super Lesser (BEL), I'd want to breed it with some of my females (such as Pastel, Pewter, Pinstripe, etc.). If I only had three females lined up for him and a friend of mine asked to do a breeding loan between one of their Normals (or morphs) and my BEL, I'd be ok with that, but I'd still want to breed him with my females. Because of that, my friend's female would be given to me for the breeding season to breed with the BEL. That way, my females and my friend's female can all be bred with the BEL.
Also, if you're worried that the female will need time to adjust, you can always send your female a couple months in advance to give her time to adjust.
