The physical justifications for the female orgasm have always seemed anti-feminist to me.

A woman is more likely to have sex if it's pleasurable, right? The only necessary evolutionary justification for the female orgasm is that it makes women more likely to want to have sex. The search for a "reason" for the female orgasm is based on the unspoken (and probably unconscious) assumption that it doesn't matter whether a woman wants to have sex or not...a decidedly patriarchal notion.

Pardon me for being just a bit skeptical about evolutionary explanations for behavior, but is there any actual evidence showing that women who have multiple orgasms are more likely to conceive than women who have none? One of the big problems with these lines of argument is that they can be used to justify anything, if you're creative enough. Most "examples" of adaptive behavior are completely unscientific (since they can't be tested) but this one could be the subject of an experiment (assuming that you could get a willing subject pool). But I'd like to see some actual evidence rather than reasonable-sounding explanations that may or may not have a basis in the physical world.
