Tantric sex tutors will help lead a "mass love-in" at Erotica 2002 in London next month.
Organisers claim the daily tantric workshops will be "one of the most extraordinary sexual experiments ever undertaken".
But security guards will be present at the London Olympia venue to ensure passion does not boil over in public.
Erotica chief executive Savvas Christodoulou said: "They say that great sex is all about mind over matter. We will put that to the test with a huge public experiment.
"With practice many people can experience ecstatic sex without any physical stimulation.
"Our security staff have been given strict instructions to ensure that our guests do not get carried away and take matters in to their own hands.
"Extra staff will be on duty during the coaching to ensure that there will be no breaches of our license - or the law."
Advance ticket sales are said to have hit record levels for the show, which takes place at London Olympia between November 22 and 24,
It will feature more than 200 exhibitors offering a range of products and services from fashion and footwear to art, furniture, body art and lingerie.
