My iguana ?

ok, i recentaly got a baby iguana (on saturday) and i have been handling it regularly so it knows im it's owner and so it can get comfortable around me, today was teh first day i took it out of it's cage for more that just holding it, i took it in the bathroom after i made sure it was "iguana proof" when i set it on the floor it didnt move just watched me, then i picked it up and let it climb up my shirt (thats wat it seemed it wanted to do) it started to climb toards my hair (my hair is red, if that has anything to do with it) it did seem to lick my shirt a few times, every time i tried to take it off my shirt it would want to go back, it was trying to climb all the way up, towards my face, i would have let it but i dont know wat it would have done, it didnt seem to be acting agressive seemed a little curious though, wat was it going to do
