This is something I have been thinking about after I read an article saying that the most popular porn for women was lesbian porn.I was a bit confused by this,because even though I know women who watch porn are probably a minority of women,I thought to myself,there is no way most of the women who watch porn are lesbian/bisexual,because women who identify as lesbian/bisexual women are a very small minority of the female population.

So I started doing some research about female sexuality,and I came to the conclusion that Hetereosexual women's sexuality is inherently more fluid than men's sexuality.

Studies were scientist do objective measures of sexual arousal, consistently show that women who identify as straight,show non-gender specific patterns of sexual arousal to sexual visual stimuli,While men who identify as a certain sexual orientation showed more gender specific patterns of sexual arousal that matches there self-identified sexual orientation.

Here are a few of those studies

Recent work supports the idea that the brains of men and women respond differently to sexual stimuli contingent upon the content of the stimuli. There are sex differences in neural activation between men and women depending upon the sex of the actor in the stimuli (Rupp, Herman, Hamann, & Wallen, 2004). While in the fMRI scanner, subjects viewed still photographs depicting male nudes, female nudes, a neutral condition, or fixation, presented in a block design. Activation to sexual stimuli was compared to activation during the neutral condition. Greater activation to opposite sex stimuli compared to same sex stimuli was seen in men in the inferior temporal and occipital lobes. Women did not show any areas of increased activation to opposite sex compared to same sex stimuli. Men showed more differential activation of brain areas related to sexual arousal than women, including the amygdala, hippocampus, basal ganglia, and some areas of the prefrontal cortex. Women did not show these differences, suggesting that women do not emotionally discriminate between opposite sex and same sex stimuli in the manner that men do. Women only showed increased activation to same sex compared to opposite sex stimuli in visual cortical areas

“Our results were largely consistent with the sexual psychophysiology literature,” the researcher told PsyPost. “That is, we found that bisexual and heterosexual women were similarly nonspecific in their responses, with neither group strongly differentiating between erotica featuring men and women.”

“We also found that homosexual women differ from the other groups, preferring female to male visual sexual stimuli. This consistency between reward system activity and the sexual psychophysiology literature supports previous studies of genital arousal, suggesting that they may have also been measuring at least some degree of positive emotional response.”

Safron and his colleagues conducted a nearly identical experiment on men and published their results in 2017. That study, however, found that men’s brain activity closely corresponded to their sexual orientations.

Heterosexual men responded more strongly to images of women and gay men responded more strongly to images of men. Bisexual men, on the other hand, did not show a much of a different response to images of men and women.

The current studies investigated within-gender variability in the gender-specificity of women’s sexual response. Two samples of women reporting concurrent andro/gynephilia viewed (Study 1, n = 29) or listened (Study 2, n = 30) to erotic stimuli varying by gender of sexual partner depicted while their genital and subjective sexual responses were assessed. Data were combined with larger datasets of predominantly gyne- and androphilic women (total N = 78 for both studies). In both studies, women reporting any degree of gynephilia, including those who self-identified as heterosexual, showed significantly greater genital response to female stimuli, similar to predominantly gynephilic women; gender-nonspecific genital response was observed for exclusively androphilic women only. Subjective sexual arousal patterns were more variable with respect to sexual attractions, likely reflecting stimulus intensity effects. Heterosexually-identified women are therefore not a homogenous group with respect to sexual responses to gender cues. Implications for within-gender variation in women’s sexual orientation and sexual responses are discussed

Also,here is another study that suggest that women are more sexually aroused by pornographic films that put them in a certain mood, instead of films that are more focused on the visual.

We hypothesized, on the basis of established observations of differing responses to various erotic stimuli and differing conditions to become sexually aroused between men and women, that women would require AVS more suited to their own preference in order to properly study female sexual function. As expected, women responded differently to the widely available male-oriented erotic films. We could confirm that—though women are aroused by stereotypical male-oriented AVS—female sexual arousal is more powerfully activated by films that better affect sexual emotions and mood (erotic movies with a concrete story and emotional stimulation). In addition, men showed more activation on fMRI when viewing stereotypical, male-oriented erotic films. Preference for a specific type of visual stimulation affected brain activation more in men than in women. We suggest that this is because women are more sensitive to non-visual or emotional stimulation and they easily link current stimuli to recalled memory. According to Jansen et al.,8 a woman’s ability to imagine herself as the woman in the film was the only factor strongly correlated with her reported arousal. Men also project themselves into the scenario, but may be more likely to objectify the actors.9 The presence of this gender difference is interestingly supported by a study of fMRI in male-to-female transsexuals.16 Male-to-female transsexuals responded more similarly to female control subjects than male control subjects during viewings of erotic stimuli.

So as you can see,there is alot of research out there that backs up the claim that women's sexuality is more fluid.Also,these are not just subjective reports of arousal,these are objective measure of arousal as well.I think the research available to us right now is pretty convincing.

After doing my research.I do believe that women sexuality is inherently more fluid than men's.

What do you guys think?
