To nerd out for a second, I think there's an interesting point made in this article (either explicitly or implicitly, I admit that I didn't read the whole thing) about physical arousal versus mental arousal. Of course we can say that the results imply that women's minds are at war with our bodies, but Slate.com made a good point about evolution and women becoming aroused even during nonconsensual sex that implies that the schism between physical arousal and mental arousal might exist for a reason. For example, a woman who is physically aroused is less likely to become torn up and thus infected and thus die after a rape, so she becomes physically aroused (but not mentally aroused) during a rape to protect herself from further injury--it's a sexual "fight or flight" response. In short, it is very possible, and probably in your best interest, for your body to say "yes" even if your mind says "no" (and that your mind is what makes the ultimate decision in regards to consent).
Also, the body tends to react in the same way to stimulus that they see, even if it's not happening to them--i.e. porn turns you on, you cry or get scared during movies, etc. So women might become physically aroused (if not mentally) to some degree (to what degree the article really didn't say) if the body thinks sex might be a possibility--which might be any sexual circumstance given that women are usually the sexual recipients and, back in the days of 'yore, didn't have as much control over their sexual destinies.
So women who say they're not turned on by bonobos (but come on those pants are AWESOME) even though their genitals say otherwise, might not be confused. They're just evolutionarily split into two sexual halves where the mind can override the body. So, in conclusion, if they say that bonobos turn them on, and the data supports it, then cool. If they say they're not turned on by bonobos, even though the data says that they might be, they probably aren't turned on by bonobos.
If I killed this thread, sorry.
Nerd out.
