I read both "The Normalization of Oral Sex" and "Open-mouthed wonder," and I think that when responding to criticisms of the prevalence of oral sex in the past, William Saletan, you could have been more explicit about the scope and nature of your evidence. The evidence to which you refer is no older than 1970, and you do not explicitly cite evidence about sexual activity before that time.

Your explanation that the "stigma" about oral sex fading is supported by your data -- but you gloss over the difference between stigma and reported incidence. Stigma is measured by people's attitudes towards sex -- frequency of sex is measured by reported incidence. There is probably a correlation between these two metrics, but you do not make that correlation obvious.

That said, I enjoyed the article, and I would appreciate a deeper study of approaches to the fading stigma of oral sex.
