The term "transsexuell" is a misspelled version of the English word "transsexual." In the context of porn video tags, it refers to content that features individuals who have undergone or are in the process of transitioning from one gender to another. This can include pre-operative, post-operative, or non-operative transsexuals. Transsexual pornography aims to cater to viewers with a preference for this specific niche within the adult entertainment industry.
