Every Friday on the blog, I answer people’s questions about sex, love, and relationships. This week’s question comes from a reader of the blog who was curious about why so many heterosexual men pleasure themselves to pornography featuring transgender or transsexual performers.
I run a porn blog and I keep getting messages from men wanting to see tranny / shemale porn. I'm assuming these men are all straight-identifying, but maybe that's just my gay-identifying bias. I'm wondering what, if any studies or knowledge is out there about men who are attracted to and watch this kind of material or even look for them in real life? It does absolutely nothing for me, but this particular fetish is unavoidable if you frequent any kind of porn social network and it seems a lot of people are into this. What are your thoughts? Why might this be a turn-on for some, and what does it imply, if anything, about their sexuality?
While the terms “tranny” and “shemale” may be commonly used on porn sites to describe a specific genre of porn, many within the trans community find those terms offensive. They aren’t typically used in the scientific literature, either, so I'll stick to more commonly used terminology here, such as “trans” and “transgender.” That said, you are correct in noting that a large number of men appear to be interested in trans pornography and the first psychological research on this topic dates back several decades.
The term gynandromorphophilia is often used among psychologists to refer to men who are attracted to “feminized men” . When I say that these guys are into "feminized" men, what I mean by this is that they are attracted to men who physically possess both male and female physical characteristics. Thus, the sexual interests of gynandromorphophiles typically include either male-to-female transsexuals or male cross-dressers.
Although men with such interests are usually stereotyped as being gay, this could not be further from the truth. In fact, research has found that the vast majority (73%) of men who have sex with male-to-female transsexuals identify as straight or bisexual . Likewise, persons who run trans porn sites have reported that most of their clients are straight men and that they have next to no gay audience at all .
Why are some men gynandromorphophiles while others are not? We can’t say why with certainty because relatively few studies have been conducted on this topic. However, research has revealed that, for a lot of these men, the appeal seems to reside in the fact that there is something inherently exotic about transsexuals and that transsexualism represents a unique combination of masculinity and femininity in both appearance and behavior. Here are some remarks made by men about what attracts them to male-to-female transsexuals:
“An exoticness, a uniqueness, something that can’t be obtained elsewhere. They’re just totally unique in their sexuality in that they’re both…men and women and at the same time, neither men nor women. To me that’s my fascination.” 
“I like the girls with a little something extra, you know what I mean.” 
Is gynandromorphophilia a fetish? The jury is still out on that, although some have noted that it co-occurs with other erotic interests such as BDSM with some frequency . For now, the most we can say is that attraction to feminized men is a distinct erotic interest among men that is not uncommon. Also, there is no reason for it to be pathologized or stigmatized, and, contrary to popular belief, men who have such interests tend to be masculine themselves and usually do not identify as gay.
