An elderly Naked Education contestant insisted they "look better now" as they disrobed in front of teenagers.
The aim of the new Channel 4 series is to get rid of the taboos surrounding bodies and help to educate the nation about 'real' bodies and what they look like.
However, the show - which is fronted by Anna Richardson, Love Island's Dr Alex George and Yinka Bokinni - has received hundreds of complaints over adults being naked in front of kids aged 14 to 17.
