A POLYAMOROUS events planner has revealed her quest to organise the world's largest orgy - inviting 1,000 to the marathon sex party. Pearl Derrier, 29, from Denver, Colorado, goes to orgies at least once a month as one person can't fulfil her "every physical and emotional need". Her partners, boyfriend Dan Patrick, 35, and "homemaker" girlfriend Tomi Tailey, 30, are also happy for her to have casual liaisons with other people at orgies.
