During a class on male anatomy in a sex education programme called "body positivity", Naked Education students, aged between 14 and 16, were surprised when four men began to strip in front of them.
The programme is hosted by Anna Richardson, along with presenter Yinka Bokinni and former Love Islander Dr Alex George. The episode, which aired on April 11 on Channel 4, has sparked outrage among some parents who believe it is "filthy" and "not necessary", with concerns specifically about nudity in front of children.
According to the Daily Star, the topic of male bodies was brought up in class this week, and the boys agreed that discussions about penis size are "more of boasting" and "a competition." One added, "Boys definitely do brag about their penis size a lot."

When they were asked of the size of "an average penis flaccid", they said "five inches". But they were shocked when Yinka and Dr Alex asked four male models to de-robe in front of them.
Lara, 16, blushed and said: "I've never seen a full naked man before." Amelia, 14, put her hands on her face and looked away: "No, I don't look at naked men. It's just a lot of naked men in real life to process. We've never really seen it! It's interesting to see how the same thing can look so different."
As for the boys, Elliot also didn't know how to respond, adding: "Just don't look at anything, just eye contact and look away." Yinka said: "I hope that the teens take away from today that nobody is out of place, that you can fit in, that you can stand out, but that is all okay."
Dr Alex said: "I can tell you the average penis size in the UK is around three inches flaccid. "If three inches doesn't sound like much, be assured, fellas, there's another 2.5 inches inside your bodies. And if you are worried your todger's overactive, it's normal to have up to 11 erections a day and four at night."
