"It doesn't have to be tying up your partner or placing clamps on their nipples, it could be something as simple as cooking a meal together or even doing the housework as a duo," psychologist Richard Wiseman says in a New Scientist article where scientist Brad Saragin measured hormones at S&M events in Colorado & Arizona and came to the conclusion that spanking can bring couples closer together.
Ummm... Mr. Saragin and Mr. Wiseman, I don't need funding to tell you that my husband & I have bonded over two naked asses and a spatula. And for the record, cooking a meal together or doing the housework as a duo is much more complex than tying up my partner.
