He does it everyday, he humps his bed and any toy big enough to fit under him. I think it is a dominance thing? He mostly humps when I move his bed from one place to another, as soon as I put it down, he starts humping it. Today I took a toy from his bed, and he gave me a funny look, like "where are you going with MY toy?" Then he started humping his bed, only this time he wouldnt stop!
I took his bed away and he moved to the other bed and started humping it. His "thingy" was out

so is this a sexual thing now? He's 14 weeks old
