Hundreds of swingers have been putting up their tents as this year's Swingfields festival gets underway.
Europe's biggest swingers party has come to the UK again for three days as raunchy revellers get into the swing of things.
Swingfields' location for this year’s “Aurora” event has now been revealed using handwritten "SF this way" signs around Malvern in Worcestershire, around an hour from the Welsh border.
The site had been a closely-guarded secret and ticket holders who pay £170 for couples are only told 48 hours before the festival gets underway.
Organisers are providing free sun cream to stop revellers being burned.
Drone pictures of the field near the Three Counties Showground - opened by the Queen in 1958 - show a red double-decker party bus and gazebo covering several double-beds.
Large hammocks, big enough for several people to swing on, have been placed in the centre of the site for attendees to relax on. Other snaps showed four poster beds dotted around the site.
Paddling pools have also been erected around the festival with a line of chairs set up nearby so that crowds can watch others make a splash.
The official Swingfields website states: "This three-day event will be working alongside ALL lifestyle groups, including LGBT communities, to ensure we deliver a fun and entertaining event for all.
"We have luxury showers and toilets available, and for those self catering this year we also have washing up facilities.”
Organisers are also offering glamping pods complete with bedding included to allow revellers to “just turn up and relax.”
Residents in the area say they are happy for the sex festival to go ahead as long as the revellers don't leave the compound.
Sylvia Hartley, 40, said: “I’m not bothered what they do inside the festival as long as they don’t leave it — but why would they?
“The festival was here last year and no one seemed to have any problems. It’s just people having sex in the open air.
“There are far more unhealthy pursuits people can do. If I wasn’t in a committed relationship I’d be tempted to go along myself.”
Last year, after months of persuasion, married couples, single women and others opened up on the swinging lifestyle in Wales, which you can read about here.
Guests have to agree to a strict set of conditions and adhere to the festival's privacy guidelines meaning they cannot use their phones in the venue, Gloucestershire Live reports.
Wristbands
Like most festivals, paying guests are issued wristbands on arrival.
But unlike most other festivals, these different-coloured wristbands here tell others what that person's sexual preference is.
Dogs
No dogs are allowed at the festival because the site is located on a farm.
Dress code
It might come as a surprise that the venue imposes a dress code on attendees.
The organisers say: "Although the dress code will be very relaxed we will expect bottom halves at least to be covered whilst in the festival arena."
Phones
There has been a crackdown on the use of phones following a change in policy in 2015.
The organisers say: "To prevent any invasion of privacy we ask that NO PHONES are used in the festival area whatsoever.
"You may use phones in the privacy of your own tents ONLY. Any phones seen being used other than in the car parking area will be confiscated until you leave."
Single men
Single men can attend the festival - but will need a bit of luck to get in. Just 10 per cent of the tickets go to unattached males.
They will need at least four people to verify their identity and suitability before being granted access.
The website says: "We welcome single gentlemen, and put a limit of 10% of the total guests, so tickets sell quickly.
"However, we do request that before booking you email us to provide your profile name on lifestyle sites so we can cross check your profile pictures and verifications.
"This is to ensure you are not a member of the press, and have been suitably verified by at least four different people.
"It is important to ensure the security of our female guests and to make sure our gentlemen guests understand the basis of the lifestyle as being respectful and polite.
"Failure to follow this process will render your ticket invalid until these requirements are met, and tickets once purchased are non refundable."
There is also a glossary of terms issued to festival-goers, including the meanings of 'full swap', 'bull', 'unicorn', and 'hot wife' - among many many more.
A 'hot wife' refers to a woman who has freedom in her marriage to pursue sexual relationships with men other than her husband.
A 'bull' refers to a sexually-dominant man who has sex with other men's wives - usually with their counterpart's permission.
'Unicorns' are single women who are interested in sex with other couples but are considered quite rare, hence the nickname.
'Full swaps' are couples who exchange partners during encounters.
