The story you are telling about your iguana makes me think he's going to have a relatively mild season. Expect some soft bites, which will likely make you bleed if here is tooth-flesh contact. The bite of an angry adult male is very violent, very strong, quick, and unmistakable. The 'Bite At' description you gave sounds just like a tentative harem-gathering impulse. He does not have any females to gather, and has no males to fight off. He only has you. Right now a green dragon stuffed toy would be good for him. Even one that is 3 feet long. Even a long green sock stuffed with terrycloth and tied off at the open end.
