A week where anything goes sexually with your partner. Neither party is allowed to say no to any proposed sexual idea, thus it devolves into some dirty whoring.

Ideally you get your friends to get in on DWW as well so you can compare notes and share ideas. More importantly it allows you to push down the shame every morning when you reflect on the prior days activities and enables you to get through the week.

You might set aside a budget because sex toys, lube and restraints aren't cheap which is how you're going to feel by the end of it all.

Also known to save many a marriage. Should be done at least once annually.
