Embarassing Bodies: What if Your Mum's Watching?

So I'm quite the fan of the C4 show Embarassing Bodies. Not because I like laughing at other people or watching gorey surgical procedures, but because despite the fact I'm not all that bright, I'm quite interested in health and I do genuinelly like medical programmes - documentaries, not dramas like Casualty that is. Still, despite the fact I find it interesting, I hate looking at the bits where they do operations on people. Hats off to doctors and surgeons everywhere, I could not do it.

Anyway, my question about Embarassing Bodies is this: why are you too embarassed to visit your own doctor in private but not too embarassed to go on national television aired to millions of people and potentially get your genitals out? I don't know if people get paid for going on there and having their cases shown, but surely your dignity is more important than money? Yeah, it's not all genital problems, so people who have feet or skin problems or stomach problems, I can understand, but if I had a gammy vagina or a swollen penis, then I'd be much more comfortable visting my own doctor in the privacy of their office as opposed to getting it out on national TV.

It's also a case of you don't actually know who's watching it as well, your colleauges could be watching, if you're a teacher, your students could be watching, your in-laws could be watching, even worse, your parents could be watching it. I suppose you might warn them not to watch it, but that's not actually physically going to stop someone you know switching it on and being grossed out or having a good laugh over the size of your penis or the state of your bikini line.

Obviously it looks like the people on there get better medical care than what they would if they went to their own GP, and I don't actually know what goes on behind the cameras, whether they're referred to private specialists or if they have treatment on the NHS or whatever, but I still don't get the general concept of going on national television with an embarassing illness and presenting it to the country, as opposed to just keeping it between you and your GP.

I will admit, the show gives out some good health advice, and nearly all the cases I've seen on there are sorted and treated very well, but I'm just saying I'd much rather visit my doctor in private than go on TV with an embarassing illness. I'm in absolutely in no way criticising the show, just the idea of why people go on there confuses me. Like I said, maybe they get paid, maybe they get better treatment, maybe they do it for the benefit of others who have similar illnesses, maybe the benefits of getting your genitals out on TV outweigh the costs of it, but even so, I think I'll stick to seeing my GP privately if it were me.
