It is, however, a claim that Sell denies.

He's right that the question he mentions seems really bad, ignoring cognitive dissonance. (I'm assuming here that he describes the order correctly.) But he shows no awareness that according to Conley et al:

Although women orgasmed only 32% as often as men in first-time hookups and 49% as often as men in repeat hookups with the same sexual partner; they orgasmed 79% as often as men in established romantic relationships (Armstrong et al., 2009)."

So to answer his question: Yes I think you could get positive response rates about equal to a women asking men for sex, if women knew you gave them orgasms ~100% of the time! Just how different do you think their brains are? I was given to understand that orgasms, and also failures to obtain one, are neurologically similar.
