Why do some men like spanking women?

The other day I got home really late and my boyfriend was up. Still waiting for me. I was kinda drunk and laughing all the time. He was trying hard not to laugh and be serious. He pulled me by his side and he sat down on the couch. After that, I was over his knee in no time. He actually started spanking me and lecture me about the fact I was late and drunk. Double trouble. Bla bla! It kinda hurt and I told him to stop but damn I wanted more. He didn't stop immediately though.. Anyway this never happend before and now I can't stop thinking about it. Lol
