I have a 15 yr old male ig that I've had since he was a very tiny hatchling, about 2 months old. He goes through mating season at least twice a year, and has never bitten or whipped anyone, except for a very stupid cat of mine who just wouldn't leave him alone, and even then it was just like a warning. He has free reign of the house, and hasn't had a cage since he was 2. Not all males are vicious during breeding season. Actually, mine is rather comical.
Rather than biting, he just will grasp on to things with his mouth, not letting go until he finishes his business. But he only does that to stuffed animals and any pair of jeans he finds laying on the floor. You can always tell when he's about to do that kinda thing though. He does this particular head bob as he slowly moves towards the object. A friend of mine had a very angry female ig, so it's not just the males. My ig is a big boy, but he's as gentle as a cow. He's even very good with my 2 year old daughter, probably better than my cats or dog are. But I have socialized him on a daily basis since he was a baby, and handled him as much as I can. It took a lot of work, but he's the best pet I've ever had.
