Why not just let him calm down in his own barracks for a bit first. Try a week or 2. Then supervise him, and try him back in with the girls? Maybe little periods of confinement will just help his todge recover and settle him down a bit.
I know no one will take this serious but why not buy a teddy like I have. It can be like a testosterone relief item (nudge nudge wink wink) and it's soft so it won't hurt him how ever much he butts and bites. Think of it like a sort of 'stress toy' for him.
...laugh you may but it might be good for him if he's in his own enclosure for a bit...xx
