How who/what we are conditions what we are able to bear to read

Imagine that Dolores, the pre-adolescent girl beloved of Humbert Humbert, in Lolita were a Labrador Retriever bitch--a dog, not a girl. That is the extreme degree of nauseated abhorrence that I, as a gay man--as God made me--naturally feel at the suggestion of heterosexual, man/girl (or, for the matter of that, woman/boy) paedophilia. Frankly, I can't get past the first paragraph, and don't want to. I am unmoved by the beauty of Mr. Nabokov's language; I just want to go somewhere and be sick.
