Ever since I started attending university and had full access to the Internet, I have developed a new fetish. I want to be treated like a baby. I have a girlfriend. We have been together for over three years now–almost as long as I have been reading your column. I want to tell her about my thing for infantilism, but I don’t know how. She took my experimentation with wearing women’s underwear pretty well, but somehow I think this is a bit more extreme.

A man who wears women’s underwear is transgressing against what it means to be an adult, fully sexual male by wearing the panties of an adult, fully sexual female. While most women experience a short “my boyfriend/husband must be gay!” freak-out when they learn the guy they’re dating/married to likes to wear panties, most calm down after they’ve been reassured that men who wear women’s undies are, almost without exception, straight guys. (The ones to watch out for, ladies, are guys who wear jockstraps when they’re not at the gym–particularly brightly colored jocks. They’re the ones smokin’ pole behind your backs.) But a man who wants to wear diapers and be treated like a baby? He’s perceived as transgressing against what it means to be an adult, period, by sexualizing infants. Most people are going to be uncomfortable with that–and rightly so. Eroticizing infants is not something any responsible adult should casually sign off on.

But, out adult babies will cry, infantilism does not eroticize infants! And they’re correct: infantilism eroticizes the way infants are treated–the intimacy, the diapers, the powder, the plastic underpants. And, of course, the powerlessness. As with most fetishes, infantilism is about domination and control. Baby babies are helpless, totally dependent on their parents; they can’t even control their own bladders. Adult babies are turned on by that extreme-yet-cozy degree of helplessness. The humiliation of being treated like an infant is the turn-on; there is nothing erotic for adult babies about actual infants. People who find infants erotic rape them–they don’t dress up like them.

When your readers came up with a term for a woman fucking a straight guy with a strap-on, I never thought that I would see “pegging” anywhere outside of your column. I just read an excerpt from the short story “Guts,” by Chuck Palahniuk, in Playboy, and the word appears in the proper context. I guess your column gets around.
