Well yeees, for a given meaning of "turns them on"...
What I meant was, imagine a hypothetical party or nightclub scenario with equal numbers of single straight men and single straight (ish) women, and you did a survey by asking all the men "which of these women would you have sex with?" and vice-versa. Now I would guess, purely based on my own experiences and observations, that the average number of women each man expresses an interest in would be higher than the average number of men each woman expresses an interest in. That's what I meant by "more selective".
Bear in mind that women having an increase in vaginal bloodflow while watching bonobo-porn presumably does not imply that women want to have sex with a bonobo.
Bear in mind that women may not want to have sex with the bonobo from the movie, but they may be aroused and want to have sex in one form or another--with themselves or another human-- after watching bonobo sex movies.
Because women aren't so literal-minded, like children, or men, that they need a pictogram of exactly the sort of things that go on during homo sapien sex or masturbation (nor do they need painfully ugly and top lit close ups of scrotums bouncing against labia) in order to get turned on. Suggestion works.
Hell, women may even be able to abstract the bonobos right out of the movie, and not even really be thinking about bonobos when they see the bonobo sex, but instead be instantly transported to a state of arousal where they are more interested in their own sexual pleasure (usually auto-erotic) than they would be in looking at pictures of
anyone/anything.
Re being picky, Just being pickier about who you decide to fuck doesn't mean you have a lower libido. For millions of years, before you had safe, legal, accessible abortions and contraception widely available, it was women who were left holding the bag (a screaming infant) after a night of sex. The high likelihood that a child has of sharing some of its father's traits means that most women don't want to be left taking care of a little douchebag replicant. So most women try to "mate" with men they find attractive on multiple levels, not just the physical one, because they're effectively always forced into thinking about potential mates as potential fathers for their offspring. Women now are probably going to tend this way, toward being picky, due to our biology having formed around this strategy over millions of years, despite having access to better pregnancy planning methods. Men, now, as always, walk alway from a recreational sexual encounter more likely to be unscathed by said screaming infant.
