This porn video tag refers to a specific genre within the adult entertainment industry. Here's a clear description for an adult audience experienced with porn videos:
"Trans-Boy-Pussy" is a term used in adult content that generally describes scenes featuring transgender males (often referred to as "trans men," or "FTM" for Female-to-Male). In these scenes, the performer may have undergone hormone replacement therapy and/or surgeries to masculinize their appearance and body. The content usually showcases the male-presenting performer with a female partner, engaging in sexual acts that focus on their feminine-appearing genitals (referred to as "pussy" in this context). This tag is intended for adult viewers who are specifically interested in content involving transgender males and their interactions during sexual encounters.
