You need to get laid, when I was playing the game, I never thought in Elizabeth in such way. Not only she wasn't Booker's love interest for obvious spoilerish reasons but she was simply too adorable and touching character to ever think of her this way. She is beautiful in a classic way, not porn one.
But given your gallery, I suppose that you must be quite sexually starved individual, please die.
Well, that's a bit rude. I empathize with your more protective instincts towards Elizabeth, but I still found her to be a very attractive and desirable woman. I have make it a point going forward to not invoke or imply a sexual relationship with Booker, but that doesn't mean she has to be a nun.
