Dermot O'Leary was visibly shocked on Friday's This Morning as he and Alison Hammond interviewed two women who class themselves as ecosexual.
Annie and Beth appeared on the ITV daytime show live via video link from their home in San Francisco and were keen to explain what it means to have sex with the earth.
As the conversation began, Dermot and Alison appeared to be trying not to laugh as the couple described different ways in which people can pleasure the planet.
"A lot about ecosex is just really paying attention, it's allowing the sensual pleasure to multiply," they said.
"You can be ecosexual and also heterosexual or homosexual or asexual, it just means that you enjoy taking pleasure with the earth."
Annie and Beth continued: "When you go for a walk you're giving the earth a massage with your feet. And you're enjoying your E-spot, your E-spots are eco sexy spots like for example, appreciating flowers as the reproductive organs of the plants."
"You might even practice grassilingus, but that's pretty advance!" they added as Dermot quickly chimed in: "Well yeah, I don't think I'm there yet! I mean, I'm open, don't get mw wrong!"
Alison was equally as stunned and asked: "Grassilingus, did she say?" as Dermot tried to move the conversation along.
"She said those words yeah. But as it's 9 o'clock, let's maybe not explore what that means," he said.
At the end of the interview, Dermot remarked: "Editorial team literally having a heart attack as we speak!"
This Morning airs weekdays at 10am on ITV and ITV Hub.
