I don't think there is a "normal" about what we enjoy thinking/hearing/talking about, especially those involving pain/body parts and emotions we cannot or do not wish to share in. I don't like horror shows, zombies, transformations into werewolves or vampires, etc. for the same reason and feel embarrassed others seem to enjoy such things. I don't like having my neck touched by even my husband, much less a vampire "kissing" me there and sucking my blood?
