Not all males - most males - and usually during their second winter, and not their first for the brumation thing.

Some young ones can just be picky, sometimes it takes scenting their prey items. If you can get your hands on a toad from outside, catch one and freeze it for a few days, come back to the toad and rub a frozen / thawed pinky mouse all over the toad to transfer the scent to the pinky. Offer this to your snake and he should take it. If you don't have access to a toad, you can also try scenting it with sardines to try and get it to eat. If you've been trying f/t, offer live and see if you get a different result. Hognose are not typically problematic, but during winter they can just turn off from food till about march.
