Greatnan Coming back to your OP, I love ballroom dancing and jive too, and sequence dancing, and I drag a reluctant MrA out at every opportunity - not that either of us have much aptitude for it
There is just something about moving in time to music which seems to satisfy some basic need and I also enjoy watching other people who are much better at it than we are, moving with grace and style.
I have only watched bits of 'Strictly' (I have to confess a weakness for Anton du Beke) but the 'dancing' seems to bear no relation to ballroom dancing as I understand it - they will perform a Foxtrot, for example, to music which is not a foxtrot tempo and isn't even a particularly nice piece of music. I dislike the theatrical aspects of it and like you, find some of it distasteful.
Wikipedia has this in its definition of 'prude':
The name is generally considered a pejorative term to suggest fear and contempt of human sexuality and excessive, unusual modesty stemming out from such a negative view of sexuality
so no, I don't think we're prudes
