Key rule Virgin Island participants and sex surrogates have to follow even after show

Here are the strict rules which participants and sex surrogates taking part on Virgin Island must follow.

The second run of the Channel 4 reality series has been more fruitful when it comes to contestants being ready to pop their cherry, with both Tegan and Ellen both going the whole way with the help of a sex surrogate.

And then there's Joy and Alex, two participants who've grown increasingly close to each other throughout the process, even sharing several kisses in a recent episode.

With two more episodes set to air tonight (18 April), this season has been at least twice as successful as season one, where there was only one person ready to have sex by the end of the show.

But once the cameras stopped rolling, the cast were all expected to follow some pretty strict rules when it came to the show's surrogates.

The rule being: strictly no contact whatsoever.

Why aren't Virgin Island participants allowed to contact sex surrogates after the show?

This rule was confirmed by season one contestant Dave, who previously explained to MailOnline that he hadn't had any contact with sex surrogate Kat after losing his virginity to her on the show.

"It was explained very clearly to us that you don't stay in touch after – it's sort of two weeks, and that's it and then you move on," he explained to the outlet.

After sharing his first intimate moment with Kat, Dave admitted that he had developed some feelings for the registered sex therapist at the time, but that he was ultimately okay with letting go.

"It's not easy to just detach from feelings, but I think it's an important lesson of it to like have those feelings and then let go of them," he said. "Which probably is one of the most important lessons."

Clarifying that he wasn't in love with the 35-year-old, he added: " I respected her greatly. I don't think I was too worried about falling in love."

While such strict boundaries may sound strange in the real world, it makes perfect sense for Virgin Island to lay out clear expectations from the get-go when it comes to participants having sexual experiences.

After all, this is Virgin Island and not Celebs Go Dating or Love Island.

As for contestants wishing to keep in touch with each other, the rules aren't as strict, with season one's Emma and Viraj going on a date after filming concluded, meaning that Joy and Alex would be able to explore their connection further should they wish to.

The final two episodes of season two of Virgin Island, episodes 7 and 8, will air back-to-back at 9pm and 10pm tonight (18 May) on Channel 4.
