Well there is one thing, according to canon, male Grimm's tend to manifest later in life. So his Grimm abilities might manifest in his mid to late twenties as opposed to female Grimms who tend to develop their abilities in their teens. His zauberbiest powers should show much earlier, however. He'd probably have his first woga as a pre-teen. So for much of his teenage life he'd basically be a zauberbiest without any sign of Grimm awareness.
