So glad you had a good time even when London was at its coldest! And yes, the Soane Museum has to be seen to be believed. After reading Tania Kindersley's description of her art crushes in the National Gallery and National Portrait Gallery, I'll definitely be looking out for paintings of smouldering Victorian chaps next time I visit: http://taniakindersley.blogspot.co.uk/2012/02/in-which-i-immerse-myself-in-art-or.html
This reminds me strangely of Richard Brautigan's writing: he had one piece of (not erotic, more meditative) short fiction imagining he was a pavement being walked on by the shoes of ladies. I haven't thought about that for years!
