If we are talking about Finnish Iron Age, I'd bet most of the people had considerable wilderness experience. Even the families living in settled houses had a habit of making two or three wilderness trips each year - spending several weeks on the go. For example, the area where I live now was mostly unpopulated wilderness back in the 1600's. People living in settled farms 100 - 150 km south of here had their permanent wilderness camps here - they rowed up the lakes and rivers to get here, and to reap the seasonal harvest hunting and fishing, then returning back home with boats loaded with furs and dried meat and fish.

So, if you want to have a male character with very little experience of being in the wild, you have to invent a good reason for it. Maybe he had overprotective parents who were afraid of losing their only son and didn't allow him to do anything dangerous?

May I ask that where are you from - which country? As, I have a feeling that there are some subtle differences between Finnish tradition and mainland European culture. Most notably the villages - in Finland we never quite had tightly packed villages with fields spreading around the hamlet. Here it is more like a network of single farms, connected with paths, fields and forest in between each house. Here and there it might have been tight units of two or three households, but pretty much nothing comparing to the stereotypical image of European Medieval village with inns and shops and people divided to different classes or professions. So, in Finland the forest is pretty much everywhere. Generally speaking any yard is bordered by forest, and it is the one and the same vast forest everywhere. (In a sense it still is so, altough most of the forest is now heavily affected by forest industry. But still, if you walk into the forest in the central park of Helsinki, theoretically speaking you can walk up all the way to Lappland without ever leaving 'wilderness' - provided that we count any lake, river, clearcut, thicket, bog and forest as 'wilderness')
