Ok just found out, this bite the guy took was a 'breeding' bite from a male that wanted to fight for a girlfriend lol.
So for all of us with males, watch out if your boy gets all rambunctious and wants a girlfriend. He might decide to take out his male frustrations on you lol.
That's a good point, even a chill male neonate can turn into a major doo-doo head once puberty hits - kind of like human males...
