BLUE TONGUE SKINKS

Hey got another question, sorry for all the threads first time owner so have a loto f worries and questions, i know they aren't good climbers but everytime i hold my skink he loves to climb upto my shoulder and sit on there, when he does i have my hand there at all times so if he falls its only about 1 or 2cm onto my hand, is there a reason why they do this? and he absolutely loves to climb all over my face aswell when im sitting down or laying down.

Also with poop, i know he is pooping regularly and every day but i have a question about when they poop/pee on you, when they do that do they do that out of fear (scared shitless) or they do it because they are relaxed/feel safe or is just because they have to poop?

Oh and one last think, when i take him out he loves to run all over up and down me to explore me but if i place him on the couch or bed or something he just sits stills, doesn't explore or anything, is that normal?

thanks for the help in advance

Today he has decided to poop/pee on me once and then pee on me again, he seems to enjoy to pee and poop on me a lot dirtying my shirts.

i think it might be when they have to go, they just go, i've had lots of times where Sly has pooped on me and i figure it just must be when they need to go. they usually poop pretty regularly so if i know he's probably gonna poop that day then i wont take him out of his terrarium unless i have a towel.

Mines still a wee baby so he poops everyday, i thought i had his routine down as past few days its been roughly 3 in the afternoon that he poops but today he did it earlier so i guess i will just keep him wrapped in a towel so i can have some clean shirts again, thanks, nothing worse then him sitting on my shoulder and then i feel a wetness go down my shoulder/chest.

Edit: heres the cheeky bugger now.
