Sometimes some folk seem to have things pretty mixed up in this country. ( I'm not saying anyone in this thread is mixed up in this way
!) Some folk get worked up about breastfeeding in public, some get worked up about seeing naked bodies in a documentary/health programme, some find it very hard to have any sort of conversation about sex.
More honest discussion ( I didn't watch the programme so don't know exactly how it would be categorised) can only be a good thing to bring our kids up to have a healthy balanced view of sex and relationships. I remember being very roud of my son's sensible attitude at the age of about 11 when he informed me in a matter of fact way that he had explained what periods were to a younger female schoolmate after someone had told a joke that referred to them and she said she didn't understand it. ( Hope he got it mainly correct!)
On the other hand, porn is very readily available in various formats. I don't think the porn industry needs a channel 4 programme to help promote it - it's managing just fine! Sadly, many prominent people, including politicians, have been found to indulge in watching or making the most extreme forms, including the abuse of children. What happens to them - they get "found out" after they're dead and files are "lost" or subject to a D notice to hide them.
Sorry to get so serious, but I do think we need to do far more to catch those who use and abuse others in the porn/sex industry - one form of modern day slavery.
