both gay and straight brains exhibited different patterns
Safron et al. (2007). “Comparisons of activation to preferred sexual stimuli, non-preferred sexual stimuli, and sports stimuli revealed large networks correlated with sexual arousal, spanning multiple cortical and subcortical areas. Both homosexual and heterosexual men exhibited category-specific arousal in brain activity. Within the amygdala, greater preference-related activity was observed in homosexual men, but it is unclear whether this is a cause or a consequence of their sexuality. In a subsequent analysis of regions hypothesized to support arousal, both participant groups demonstrated widespread increases in evoked activity for preferred stimuli.”
Schiffer et al. (2008). “The results for the sexual > neutral block contrast in the boys condition, together with the appendant regression analyses with sexual arousal ratings in homosexual pedophiles, confirmed an activation pattern previously reported in heterosexual males.”

dubbed it the “Sleeping Beauty” fetish
. Bianchi-Demicheli et al. (2010). Intriguingly, there is an online genre of pornography that features sleeping women, including sites like
SleepingLand.com
,
3XSleep.com
, and
SleepingPortal.com
. Though most of the interest in this genre is probably due to natural urges rather than brain damage, perhaps
some
of these Sleeping Beauty fetishists have the same brain lesion as Ortigue’s fascinating patient.

We analyzed 1.9 million men-seeking-men ads on Craigslist
Posters are disarmingly direct and top or bottom self-identification is commonly made in the short post titles itself (for example: “Suck your cock and more,” “Submissive cocksucker in hotel,” “Use my mouth,” “Looking for masculine guy who like to be serviced,” “Smooth white bottom for hung top”). We took advantage of this feature to categorize posters as tops and bottoms by conservatively matching titles with string patterns. A small random sampling of posts that did not match any of the string patterns showed the distribution to be same as obtained from pattern-matched titles.
Interestingly, we also found that posters lie about their age. The most commonly reported ages are 28, 35, 30, 25, 38, and 29, suggesting a tendency toward rounding off toward milestone numbers when above, and subtracting when close. About 30,000 ads among the 1.9 million were posted by married men. This was also determined by pattern-matching the titles.

about 2 percent of them specifically requested men willing to dominate another man sexually
At least 1.6% or 31,667 listings out of total 1.95 million m4m craigslist posts seek out sexual domination. This was determined by solicitations in post titles that used the keywords
rough
,
rape
,
slut
,
whore.
These keywords were chosen after verifying that such usage was highly correlated with requests for sexual domination.

Also see Albright (2008). Based on a survey of 15,246 respondents in the United States 75 percent of men and 41 percent of women had intentionally viewed or downloaded porn. Men and gays/lesbians were more likely to access porn or engage in other sex-seeking behaviors online compared with straight men or women. Also see Cooper et al. (2003).

different set of erotic cues
Kruger & Fisher (2005). Female college students read brief sketches of characters from nineteenth-century novels exemplifying alternative male mating strategies. The proper hero “dad” advertises high potential for paternal investment by being compassionate, romantic, and industrious, whereas the dark hero “cad” advertises high genetic quality by being competitive, dominant, and brave. Women preferred the “dad” for long-term relationships, but were more likely to choose the “cad” for brief sexual relationships. These preferences were expected, as they benefit the women’s reproductive success. Participants also inferred critical attributes and behaviors from the character descriptions that omitted this information. Also see Kruger et al. (2003).

she gives special preference to males with superior genes
Haselton & Miller (2006), Gizewski et al. (2006). Also
http://www.eurekalert.org/pub_releases/2010-08/uocp-mwp082410.php
: “Not unlike the chimps featured on the Discovery Channel, women become more competitive with other females during the handful of days each month when they are ovulating. The desire for women at peak fertility to unconsciously choose products that enhance appearance is driven by a desire to outdo attractive rival women.”
157
good looks and social dominance
Haselton & Miller (2006). “Comparing women in mid-luteal phase and during their menses, superior activation was revealed for women in mid-luteal phase in the anterior cingulate, left insula, and orbitofrontal cortex. The superior cerebral activation in the mid-luteal phase is also correlated with the differing subjective rating of women in the two cycle times. The women within the mid-luteal phase rated their sexual arousal similar to men and women within the menstrual phase rated significantly lower than men or women in mid-luteal phase. The reported results indicate that the differences in cerebral activation are more prominent in comparison between men and women than between women in different cycle phases.”

tips that professional lap dancers received
Miller et al. (2007). “To see whether estrus was really ‘lost’ during human evolution (as researchers often claim), we examined ovulatory cycle effects on tip earnings by professional lap dancers working in gentlemen’s clubs. Eighteen dancers recorded their menstrual periods, work shifts, and tip earnings for 60 days on a study Web site. A mixed-model analysis of 296 work shifts (representing about 5300 lap dances) showed an interaction between cycle phase and hormonal contraception use. Normally cycling participants earned about US$335 per 5-h shift during estrus, US$260 per shift during the luteal phase, and US$185 per shift during menstruation. By contrast, participants using contraceptive pills showed no estrus earnings peak. These results constitute the first direct economic evidence for the existence and importance of estrus in contemporary human females, in a real-world work setting. These results have clear implications for human evolution, sexuality, and economics.”
