I'm awfully pleased that I've discovered a real-life example that will serve roughly the same purpose. Meet Jeff (from the ABC news website, always a treasure trove of tabloid trash, mixed in with an occasional news story)--
.... for Jeff, breast-feeding seems to be the act that fulfills his sexual desire.I admit, I quoted more of that than strictly necessary. The crucial part is in blue.
"I really don't care what people think," Jeff told ABCNews.com. "I grew up to try to be a people pleaser and came to the conclusion that you can't please everyone. It works for us and we are consenting adults. And it helps me be able to perform."
"I can't explain it, but when I breast-feed, it helps strengthen my erection," he says. "When Michelle was pregnant with our son and stopped producing milk and I had to drink regular milk, during that time I was unable to maintain a healthy erection. The first time I breast-fed again, it was awesome."
And that's not his only fetish. Jeff is turned on by getting his wife pregnant and has forbid her to use any kind of birth control, even though both their children were born prematurely and doctors have warned Michelle about potential dangers to her health if she risks another pregnancy.
But his wife is just as into it. "It was very erotic," said Michelle. "Breasts are a central sexual object and milk flowing does not just have to be just for the baby. If there is excess, we might as well make use of it."
Jeff puts the sweet breast milk in his coffee and in his breakfast cereal. He's also into vampires, naming their infant son Khayman from a character in Anne Rice's "Vampire Chronicles." Sometimes he bears his teeth into Michelle's areola and sucks the blood.
Jeff prioritizes his sexual pleasure, so keeps getting his wife pregnant, even though the resulting children are born premature (and her health is threatened--not the key point, but certainly a strike against him). The question is why he and his wife are guilty of anything, as far as their offspring are concerned. I do think they are, but it isn't easy to explain why. In fact there's a huge ethics literature with relevance to this question.
Kavka's article is here, and the debate about these issues is presented in a powerpoint here ("Kavka"). Next time I teach this course, we may have to talk about Jeff!
