Couples are turning to adults-only sex cruises to spice up their relationships.
The X-rated jaunts, run by Temptation Cruises, feature everything from educational workshops to racy stage shows, but it's the secret 'red room' where the wildest antics really go down.
Cameras and photos are banned and staff are stationed at the doors to protect the privacy of those inside.
Rules to entry are strict, as only couples are allowed admission.
Once past the doors, couples have the option of jumping on one of the many circular beds - which have plastic protectors underneath the sheets - in the center of the room, or simply sitting on the sidelines with a drink and observing all the action.
Intimacy coach and hypnotherapist Kate Shelor, who runs racy seminars on the cruises, lifted the lid on what really goes down on board in an interview with DailyMail.com.
'The Temptation Cruises aren't explicitly swingers cruises, but I would say that it's probably 60 to 70 per cent people who are in that lifestyle,' she explained.
'The other 30 per cent are not, but they want a fun, sexy, adult atmosphere.'

The age range of attendees generally ranges from mid-twenties to mid-fifties, with the majority being couples, although there's plenty of singles on board too.
'I would say there's people that are there to swing for sure, then there are couples who don't interact with other couples,' Kate said.
'They don't play, they don't swing, but they may want to do something a little wild. Like, there are areas on board where you can be topless and go dancing,' she continued.
'There's a lot of people who may just want to push some personal boundaries and feel a little bit, you know, dangerous and exciting. And then there's also areas where you can be completely nude, but that is in the indoor pool area only and the rules are very strict.'
Kate also shared one of the jaw-dropping sexual experiences she hosts inside the ship's secret playroom - or 'red room' as it's become known as - where she guides up to 60 couples to orgasm together.
'I do a hypnotic sex seminar. It's couples only, but they can bring a third,' she said.
Once inside, the couples (and throuples) find a mattress to sit on together, before being blindfolded.
'Part of the experience is getting in touch with your senses, and it also means that not everybody's being watched by each other,' Kate said.

In addition to the sexy seminars, the cruises also host racy live entertainment shows

Kate then guides the couples to begin touching each other, before they eventually end up having full sex.
'So in the end, you have a room full of people orgasming together,' Kate said proudly.
The professional sexpert said that her seminars sell out 'every time' and that they're now so successful that she's had to add more to her schedule to meet the demand.
'They're asking me to do three instead of two on the next cruise because they're so popular!' she said.
When she's not guiding couples to orgasm, Kate keeps busy with her sex podcast, Dirty Little Secrets, and shares sex advice on her official Instagram page.
She also works as an OnlyFans creator, where she shares a mixture of explicit and educational content.
