A bit of feedback.
First, this MC is supposed to be a blacksmith's apprentice of some sort? Yet in that picture posted above, and in the game, he seems a bit scrawny. Those are not the arms of a guy who bangs a hammer for hours a day, or carries heavy bundles. He doesn't need to look like Conan, but some muscle definition would be more realistic.
Second, on the ideas of "rough" type sex, a.k.a. more Norse. I've traveled all over Norway and Sweden, am a Swede myself. That said, it's the women over there that are the aggressors. Truly not kidding. They might like it hard, but they definitely don't ask nice for it. They are a lot more demanding in what they want. Lots of hair pulling, prone bone, and they are very into giving handjobs in a dominate way, not in your lap, but more being over you or in a 69 type position.
Historically, Norse women were seen as being equals to men than any other ancient society. The stories of a Viking horde of men raping and pillaging village are mostly rubbish stories of victims. I'm sure some rapes did occur, but most raiding parties were composed of a comparable number of women as men, and it was seen as a disgrace to their gods to lay with the unbelievers. There were also laws with the penalty of death against taking a woman by force that was very strictly enforced. They had a strong belief in family, and these women were the daughters of someone. Harming them in such a way and an entire family, their neighbors, and likely that man's family due to the dishonor brought upon it, all would strive to end the life of the man. Thus, it rarely occurred. Even when they were at war.
