Lots of normal guys, especially in long-term het relationships, are fine with having period sex, not even including the guys who have a kink for it. But not relevant in this case anyway; he wasn’t forcing her into sex for his sexual pleasure, he was forcing her into sex to punish her for having sex with another guy.
I hate to ask this but did he rape her?
I'm guessing not since her robe was still on? But the look in her eyes gave me that feeling and technically the robe can still be on to do stuff...
