Is sexual tension related to sexual function?

It's just an excuse. I've never heard of refusing marriage by surname. This excuse is ridiculous. Since ancient times, people in China have used the zodiac, birthday, life, family background and so on to see whether the two families are suitable for marriage. It's what we call a perfect match.

But last names are so funny. You give up, it won't be happy. A mother-in-law, your mother-in-law relationship is too difficult.
