People who own a Fifty Shades-esque red dungeon of pain, and want to find a use for it when they are on holiday, or who own a honeymoon-worthy castle could now find themselves a lucrative new source of income.

KinkBNB is marketing itself as the sex-positive Airbnb - and tenants and renters alike know what they are getting into when they sign up for the site.

"Many sites offer to connect you to regular rooms, but KinkBNB specializes in adult play rooms, or accommodations with the open minded"

The Airbnb-style homesharing website now lets lovers book sex-focused getaways without stressing about waking up the next door neighbours or being landed with a hefty damages charge.
