Why is my crested gecko so bitey!?

[Keithowner123]

Hi! This is my first time posting on this website. I just want to know why my 2 and a half year old crestie is so aggressive and why when I pick him up he bites me. I think it may be that I keep his mealworms next to his vivarium and he can smell them from where he is so he thinks my fingers are for tea!

Should i I be worried about this or is this something he can grow out of? Thank you for any responses and thank you for reading.

P.S. He is my first reptile.

First of all, how much does he weigh? If he's between 10 and 20 grams, it might be a hormonal thing and he might grow out of it.

Another thing is whether the biting is sexually motivated. Is he making any sounds when he bites? If he is doing this, he's just horny:
