Ofcom flooded with complaints over Channel 4's 'obscene' sex education show BEFORE the watershed

Presenter Anna Richardson had tantric sex tuition during the programme

Channel 4 has been accused of peddling obscenity after showing explicit sexual material before the 9pm watershed.

Scores of viewers complained after the Sex Education Show, which began at 8pm on Tuesday, saw school pupils asked to discuss pornography and inspect graphic images of genitalia.

The media regulator Ofcom confirmed that it would investigate the programme, in which teenagers were seen describing depraved sex acts they had seen on the internet, before shocked parents were shown the vile footage from the web.

Other parts of the hour-long show, aired on Tuesday and the first in a series, saw a men's football team drop their shorts before repairing to the lavatories where they were said to have measured the size of their sexual organs.

In the programme a group of boys were shown close-up images of penises and asked which they thought was the average size.

A male model's genitals were also shown in close up as a female doctor described in depth the anatomy of the penis.

There were also intimate waxings and a group of schoolgirls looking at pictures of different size breasts.

Presenter Anna Richardson was seen attending a Tantric sex tuition session before she tried it out on her partner.

Parents in the programme being shown explicit internet images looked visibly shocked, with one woman looking as if she was about to vomit.

The children who took part in the programme, who attend an unnamed state school, were aged between 15 and 16. Their parents had given full consent for them to take part.

Shocked viewers said Channel 4 was guilty of broadcasting indecency into family homes.

They claimed it had broken the rules aimed at protecting youngsters from inappropriate material and said they were baffled it showed the programme so early in the evening.

Others accused the broadcaster of once again employing tawdry tactics to gain viewers.

The show had a peak audience of 3.3million, which the broadcaster heralded as a success.

The six-part series is also due to cover abortion, homosexuality and pregnancy in the coming weeks.

One viewer contacting a TV message board said Channel 4 was 'reaching new lows' and added: 'This was nothing short of legalised porn.'

John Beyer, director of the TV pressure group Mediawatch UK said he had received a number of complaints about the programme. He claimed that in his opinion what had been broadcast was 'obscene'.

Beyer said: 'People are absolutely appalled and astonished something like that was put on by Channel 4 at 8pm.

'I find it extraordinary that they could put this on at that time.

'It is so early and it seems to me that Ofcom has got to answer how this is not in breach of the statutory requirement to protect under-18s.'

Conservative MP David Davies added: 'This doesn't so much seem a sex education programme as an excuse to shock people with controversy in order to boost ratings.'

He added: 'Some people derive sexual satisfaction in the most bizarre manner.

'But do we really need to have these things graphically discussed by schoolchildren at 8pm in the evening when we are having our tea?'
