I haven't, but I am close friends with a lot of people who do and I am looking to get my own! I do have experience with iguanas though. We had one who was great...until breeding season. Warning to your girlfriend, I have found from personal experience(as well as experience of others) that iguanas respond poorly to certain hormones while in breeding season. Some people have found that when their iguana is in breeding mode and their wife is at a certain point of a womanly cycle () the iguana can sometimes react very negatively to said person! Now this is iguana to iguana basis, some don't change at all, some take down the MEN in the family during breeding season. Even perfumes can make a male randomly furious. Random lizards! Our iguana chose to wage war against everything that was male in the house. He struck at me a few times but nowhere as bad as he went after the boys! That's just our own experience though. I know someone who's never noticed breeding season cause her male just doesn't act all that different.
