Lily Phillips and 's extreme sex challenges are sparking fierce concern from experts as they continue to compete against each other.

When controversial adult star Bonnie, 25, by sleeping with 1,057 men in just 12 hours last week, attention turned to her fellow adult film star Lily. Just days before Bonnie bragged about her troubling stunt online, Lily had said she was .

Lily's plans emerged after she was filmed breaking down in tears following her own 'challenge', where she slept with 100 men in 24 hours. The viral YouTube clip of a visibly struggling Lily caused widespread fear over the growing trend of extreme content, both from experts and fellow sex workers alike. They say the saturated market, combined with a digital landscape which favours viral, shocking content, is pushing young women on the platform to potentially damaging extremes.

Some concerned viewers of the documentary even called for the platform to be banned, citing an apparent lack of safeguarding for potentially vulnerable creators. The Mirror has put these concerns to OnlyFans with no response, but the company's CEO Keily Blair has that the sex platform is 'safe', 'feminist' and 'empowering'.

The duo's competitive streaks and reactive patterns to set new potentially dangerous sex records, each more extreme than the last, are causing concerns. Therapists and mental health specialists have sounded the alarm on the long-term physical and mental health impacts that could come from their work.

Psychosexual therapist and sex educator told the Mirror that stunts like Bonnie's 12-hour 'marathon' can result in anxiety, distress and physical 'trauma'. She explained: "Even with adequate stimulation, an extremely long sexual session would make a woman vulnerable to pain, tears, internal physical trauma or at the very least discomfort would be practically guaranteed, with sexually transmitted infections being a real risk."

Lily and Bonnie appear to have once been on good terms but their relationship soured last year when Lily called out Bonnie for making "misogynistic" comments. Lily appeared on The Spills chat show and argued that Bonnie's controversial comments on sex could be harmful, regardless of whether they are said for 'rage-bait', a tactic Bonnie herself admits to using.

Responding to Bonnie's outlandish comments about her 'saving marriages' by sleeping with women's husbands, where she insisted that women must have sex with their partners to stop them cheating, Lily said: "If some girl watches that and is like, 'right, well I need to be having sex with my partner otherwise he's going to cheat', then you're just having sex for his enjoyment because you feel like you have to do it. I think if you feel like you have to have sex with someone, that feels non-consensual to me."

Now, Bonnie has spoken about her friendship with Lily, setting the record straight on where the troubling idea came from. She told Metro: "I shared my idea with Lily that I wanted to beat the world record this year… and I spoke about it way before Lily announced 'her' idea of the world record," she claimed. In October, Bonnie appeared on an episode of Dream On With Lottie Moss and spoke about the concerning challenge.

She said on the podcast: "I don't know if I'll do it next year or wait until I leave the industry, but I want to beat the world record. It's [a man] every 45 seconds… If I leave the industry, I need to go out with a bang." It was a month before Lily declared she wanted to take on the task. But have they clashed heads? Bonnie said: "Lily and I haven't spoken. I wish her all the best in her career and I hope she finds enjoyment making content."

Meanwhile, Lily told about Bonnie's sex 'marathon': "I respect it. That's hard work, so congratulations to her. I don't think there's competition and I don't feel I now have to do 1058. I feel like there's enough men in this ." Disturbingly, Lily, 23, has now turned her attention to a new extreme challenge, claiming she will instead have anal sex 'with as many guys as possible'.

Therapist Natasha tells us that that Bonnie may have used dissociation to cope with hundreds of sexual encounters. She explained that dissociation is a "coping mechanism" where the person may "disconnect" from their body or emotions as a way to protect themselves from discomfort, distress, anxiety, or emotional overload. While some people might find out-of-body experiences "pleasurable" or even "transformative" others may find them "distressing".

It's also been warned that the internet's obsession with virality could have harmful repercussions on sex workers and women in the wider society. Lily raised this issue herself in a recent YouTube documentary, remarking that some subscribers may be expecting certain things from women that don't necessarily reflect real life.

Health psychologist Jo Rodriguez, from, told the that younger "brains are not adaptive enough to recognise actually that's not the real ". She warned: "It's a version of reality that is given to you in the context of the situation. These young people, they see this, they expect this to be what relationships are like. How women are or what men are like, and then believe that they need to fit these roles. It can create all sorts of problems for both men and women because it is not an accurate reflection of reality."

Bonnie addressed her critics in a previous interview with us, telling the Mirror: "These women hating on me can't seem to understand that some women do things other than stand in the kitchen and let their husbands pay the bills. They seem to have a big issue with that. But the more hate I get, the more it increases my bank balance."

She added: "I've received a lot of death threats. Some say, 'I'm going to stamp your head in', 'I can't wait to put you under the ground', and 'I hope you get tortured and kidnapped'. They think I'm the one in the wrong, however, what I'm doing is completely legal. They want to kill me - how am I the one that needs help?"

Meanwhile, Lily conceeded that she is "part of the problem" when it comes to men's unrealistic expectations of women in the bedroom. She told : "It's so hard because doing something extreme like this is not normal. I think guys are going to expect girls to sleep with that many guys and do stuff like that - but that isn't real life. It's my fantasy but I'm not helping the situation."

Lily said thay she tries to make it clear her content is of the extreme scale and she does it because she enjoys it. She said: "I feel like I'm one of a very small percentage of women who would enjoy this kind of activity and I just try to be as honest with people as possible about that. But I'm not responsible for what men do and how they think."
