And a suggestion.. If you are backing off to him, he will learn this works and he will think he's the dominant force in your relationship.. Thats not a good thing. Some iguanas will start going after people for the weird things.. Different scent, different color.. Sex etc. A common visitor here has had experience where her nice tame iguana turned on her.. yet her husband was able to handle if If my memory is right. I do not know what triggered that reaction, I do not believe she did either.... They can be crazy creatures. Most guys have a more dominant demeanor than women (most unless your talking about my sister and her ex boyfriend lol..).. So in the case of that iguana perhaps her husband excreted more of a dominant presence to the iguana than she did.. or like I said, cloth color, scent.. Maybe he wanted to mate with her who knows now. If you have another person in the household see if there is different reactions.
When he charges for you throw a towel over him. you MUST show him who's the boss but be careful. There are kevlar gloves with sleeves sold online.. They will help protect you from bites but the sheer pressure from the bite can bust fingers so always be careful.
