Hey guys, looking for some guidance, suggestions, ideas, etc.

I'm pretty kinky & understand the dom/sub fetishes. My new boyfriend is very submissive and has a very strong spanking fetish. He wants to be spanked, disciplined, punished, etc--it's very hot, but I don't quite understand this.

Can somebody sort of explain why it may turn it on? I know part of it is being submissive, but I don't get the spanking. He has a very low pain tolerance, he's pretty small at about 130 lbs.

What can I do to really turn him on? What sort of fantasies?

Thanks guys
