This porn video tag indicates that the content features amateur, self-pleasuring scenes, typically filmed by the performer themselves or with minimal professional involvement. These types of videos often provide an intimate, personal look at the individuals involved and may showcase various techniques, fantasies, and sexual preferences. The term "homemade" suggests a more natural, spontaneous, and unscripted experience compared to professionally produced pornography.
