Male rex rabbit

Question
We got our rex rabbit (not a mini either) last july at the Piston Fair,the lady said Roxy our rex rabbit was 10 weeks old. We thought it was a girl until 2day. I was cleaning out her litter box in her cage as I do every morning, an as I was pulling my arm out of the front of her indoor cage,she climed up my arm sniffed my face an then started 2 hump my arm lol.I dont think females do that. I shook her or him off.Roxy is great with my daughters but doesnt seem 2 like my husband. Roxy gunts an scatches him when he trys 2 pat her while we pat her,or just by himself in case our presents is a bother. Why does she do that with him? An why did he hump my arm?When do they come into sexal machority?An how long do rabbits live? Thank you for listen,will wait for your response!

Answer
hi Sabrina all does hump anyone its quite common.
she obviously has taken a dislike to your hubby and it may take quite a bit of time for her to accept him
rabbits can breed at 4 month's old and all rabbits are classed as adults at 5 months old.
some rabbits live a long time but i would say the average is about 6 yrs.
