Re Edwardian attitudes to sexuality:
The history of sexuality in society interests me greatly and it is a pity that research into it is only now being done. I've never read much on the subject directly, although what I have read bears out your comment and the programme you watched.
Certainly if mediaeval and early modern literature is anything to go by, women's sexuality was something accepted as a fact at all levels of society. It only seems to have started going into the closet in polite society in the eighteenth century. Still, it seems to me that by the start of the Victorian era, women were already seen as sexless.
Against this is of course the dismal continuity of absolute double standards to the detriment of women. Women were expected to keep themselves safe, and "seduction by" a women was, even on the facts as admitted, simply rape of a woman. And while the often-repeated remark that women were legally the property of men is not true, it is not surprising that society should be characterised in that way.
Re the Victorians: I suspect the couple you mentioned are the Kingsleys (the husband being Charles Kingsley, CofE vicar and author of The Water Babies) and it is true that their marriage was pretty remarkable. However, they were exceptional - and very fortunate to be rich enough to have the privacy to express themselves that way. I think we forget just how little privacy people had until after the War. I think the probability is that sexual expression was pretty confined.
As for the Edwardians - I'm prepared to accept that is at the point that female sexuality became most invisible, although possibly not the time that was most sexually repressive - it is too close to the prime of Oscar Wilde and Aubrey Beardsley for starters.
For sheer out-and-out repression, I'd go for the republic of Ireland in the 50s: exemplified by archbishops censoring lingerie catalogues for being provocative - their motive being to protect men from being led into the sin of lust. Now we live in a time when people can be more open about sex - and porn, or so it seems to me, is a contingent part of that openness. I daresay there are people who would prefer no porn to exist - but that seems to go hand in hand with sexual repression - and for that matter - no contraception or abortion. I suspect that the endless debates on porn would generate more light and less heat if people took history into account.
