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 are pleasuring themselves to pornography featuring transgender and 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?
