Let's refine the proposition here: Very few (under 5 percent?) prepubescents inherently want sexual activity with adult partners -- the kind where one partner manipulates the other's genitals for sexual pleasure (an approximate definition, of course).

This does not include early masturbation. It does not include curiosity about sex and "playing doctor". It does not include a desire to learn by looking at porn. It does not include flirting. It does not include otherwise neglected kids who are ecstatic about a loving adult in their lives and who put up with some sex because that's part of the deal.

What studies go with those surnames you cite isn't entirely clear to me. The Sandfort study I am aware of does not refute the proposition. It is a highly biased self-selected sample where most reports from the boys are that the sex is OK -- not of inherent interest.

I don't recall the Rind meta-analysis addressing this issue directly. It could study prevalence of reported abuse -- including primarily pubescent and post-pubescent cases. It could report negative, neutral or positive attitudes about it, but it doesn't say much about whether it was actively desired or not -- nor of the desires of those who were not abused.

As for the others, I'll await citations.
