I think it's almost just implied with marriage in almost all cases that a woman is gonna take the last name. I think it only becomes an issue if the man brings it up. Personally, I think if a man had to make sure or double check if there would be a name change, it would open the door for cheating because he appears insecure. Men are supposed to be proud of their name.

I think the question is easy for anyone who is truly submissive to say yes, I would take the femdom's name, but for me, as someone who just enjoys seeing a woman with a strap on and her tits out, I wouldn't. I have to wonder if a truly dominant female would even marry a submissive male.
