The original text discusses the anatomy of transgender women (trans women) who have not undergone gender-affirming surgery (vaginoplasty) and debunks the myth that trans women necessarily have large penises big penis huge dick and are sexually dominant.

Trans Women and Anatomy
A trans woman (or transpuan) is a person who was assigned male at birth but whose gender identity is female.
- Not all trans women undergo sex reassignment surgery (vaginoplasty). If they haven’t, they still have a penis. Its size varies just like it does for cisgender men, depending on genetic factors, hormones, and bodily development.
- Hormone therapy (estrogen plus anti-androgens) typically causes the penis to decrease in size and erectile function; it doesn’t make it larger.
The Myth of “Large Penis = Dominant”
The belief that penis size automatically makes someone dominant is incorrect. Dominance or passivity in sex is a matter of preference, personality, and partner dynamics, not the size of the genitals.
- Stereotypes like “Mandingo” originate from pornography and racism, not biological reality.

The Phenomenon of Sexual Perception
Some people perceive trans women with penises as “unique” or “exotic.” This perception often arises from fetishization in media or pornography.
- This leads to the impression that trans women, as a group, have larger penises or are more dominant. The reality, however, is the same as for other people: some are large, some are small, some are dominant, some are passive, and some are flexible.
In summary, it is not true that trans women definitely have a large penis and are dominant. This is largely a myth influenced by pornography and stereotypes, not a medical fact.
The original question asks whether the myth comes from pornography and culture or from medical facts about the effects of hormones.
1. Myth Origin (Pornography & Culture)
- Transgender pornography often features trans women with large penises, strong erections, and dominant roles in bed. This is intentionally done by the porn industry to appeal to specific fetishes (the “shemale” or “tranny” porn fetish).
- Racist stereotypes from the colonial era and Western pornography, such as the “Mandingo” trope—associated with large penises and aggressive behavior in Black men—were also often “attached” to trans women in pornography.
- Ultimately, the public, lacking knowledge about trans people, comes to believe the myth that trans women generally have large penises and are dominant.
2. Medical Facts (Hormones & Anatomy)
- When a trans woman undergoes hormone therapy (estrogen and anti-androgens):
- Erections become more difficult, and the penis tends to shrink (atrophy).
- Libido decreases.
- Testicles shrink.
- Medically, this is the opposite of the image presented in pornography.
- The final size of the penis remains dependent on inherent genetics, not on the process of transition.
3. Conclusion
Pornography exaggerates (literally and figuratively) for the consumption of sexual fantasies. The biological reality is that trans women have diverse bodies, just like cisgender men and women—some are large, small, dominant, passive, or flexible.
Therefore, the assumption that “trans women definitely have large penises and are dominant” is a cultural and pornographic phenomenon, not a scientific fact.
