At the Berlin Biennial this year, a number of artistic endeavours examine various aspects of the city - few as show-stopping as a film about a Swedish woman who married the Berlin Wall:
"Among the broken lumps of masonry and rubbish is a shed in which a film by Lars Laumann tells the story of a Swedish woman who fell in love with the Berlin Wall and now believes they are husband and wife. In the dark, my jaw dropped. The story, I realised, is not a spoof. Eija-Riitta Berliner-Mauer really is Mrs Berlin Wall, and lives with her now retired husband, in the form of various small barbed-wire-topped models of himself, in a village in northern Sweden. She says the day the wall came down was an absolute disaster, but she loves her wall just the same. As well as her beloved husband and numerous cats, she also keeps various scale-models of guillotines for company. What turns her on is parallel lines, rectangular shapes, forms that divide (such as walls), and others that connect (such as bridges). Don't ask about the guillotines. She says she's an object-sexualist, and believes that objects have souls, feelings, desires and thoughts they share with her telepathically."

There are even people who 'get off' on things like mathematics, religion or nature.
Sexuality is so fluid and diverse that it shouldn't be pigeon-holed into one model. Let your freak shine!
She must probably be also turned on by their historical value or their severing qualities: guillotines... Berlin Wall... They all split something in two.
But I suspect she's got issues with other people. Trust issues and the like. And I could see that her love for something that is a barrier, a divider, might be a bit symbolic of boundary issues. I'd be willing to bet she was abused. But, like Freud said, "Sometimes, a cigar is just a cigar.". Might benefit from therapy,though.
Also, I wonder if it's just some objects that are ultra significant, but all objects are significant, or just that handful of objects that matters. Is it just the wall and the guillotines that she's in telepathic communication with, or is it everything? In a way, that would be sort of zen and a little bit cool, a union with all the matter in the universe type thing, but would seriously make life difficult for her.
