NAKED Education viewers have demanded the show is pulled off air after men stripped off in front of teenagers.
The brand new Channel 4 programme is aimed at "celebrating diversity and body positivity".
But since it has started, it has proved highly controversial with viewers at home.
It is presented by Naked Attraction's Anna Richardson, with Yinka Bokinni and Dr Alex George also appearing.
The latest episode saw a discussion on the topic of male bodies - with the teenage boys being asked about the average size of a man's penis.
During the segment Dr Alex and Yinka asked four models in front of the adolescents to de-robe.

The men then revealed their naked bodies to the stunned group.
However, the scenes have left some viewers furious and branding the whole thing as "wrong".
One said: "This is absolutely vile and disgusting and any parent who thinks this is normal needs looking into."
A second wrote: "This is wrong! Random adults baring naked to kids, absolutely wrong!"

"How is this being allowed to air on national TV," said a third watcher.
While a fourth commented: "So we are now having naked men stand in front of our children. Disgusting."
Since the episode aired, nearly 1,000 viewers have complained to broadcasting watchdog Ofcom.
Despite the outrage from some viewers, others have praised Channel 4 and programme bosses.
They said it was "so important" and also educational, which was "empowering" to younger teens.
Naked Education is available to stream on All4.
