He looks lovely

I would just ditch the ball to start with, your male shouldn't be getting that close to your female & it won't help with taming.
Either set up a playpen/safe play area away from your female & put lots of toys & maybe a wheel in there for him & let him play in there instead, if you make it big enough you can sit inside with him or if not you can interact with him sitting by the side, alternatively some people use the bath (plug in & towel in the bottom) as a taming area.
Just because he's not happy & behaves that way in close proximity to your female doesn't mean he will be aggressive toward you so don't be afraid of taming him.
