I’m reiterating what I wrote in response to another thread because I was wondering if anyone had similar issues pre-neutering!
I now refer to my precious mini lop, Miles, as my Little Psycho Nutcase because he went completely and utterly bonkers once bunny puberty hit. Started with some honking and nipping, then digging at my arms and trying to hump them (ignoring my attempts to transfer the urges to a teddy bear), then he started forgetting how to poop in any litterbox outside his cage, then he learned he was big enough to jump on my bed and couch which led to him feeling the need to pee all over both, even if he was only up there for a second before I scooped him up and moved him down. If I block him from getting up to where he wants to go and pee, he stomps his foot and hops away! COME ON!!
Covering my bed in puppy potty training pads is getting a little old, but it’s really breaking my heart because I don’t want to hang out with him anymore. All he does is nip at me (and it hurts!), dig at me, and poop and pee all over the darn place. Where did the little bunny who used to fall asleep in my lap go?!
He had pretty much mastered litter training prior to this nonsense starting, and was the sweetest little thing you could ever imagine. He’s still as friendly, but now his wiring is driving him towards different goals once he gets close to the people he thinks he wants to hang out with. This is my human interpretation 
I’ve been literally hoping and praying that his little bunny testicles would descend so my vet will neuter him. Today I checked, and there they were! Cue happy dance!
I’m sincerely hoping that someone else out there had a bunny who went insane, but then made a full recovery after a little snippage.
