Inside Porn Videos
"Inside" in the context of a porn video tag typically refers to a specific type of sexual activity. It usually means anal sex, where one partner's penis is inserted into the other partner's rectum. This can be between any gender pairing (e.g., male-female, female-female, or male-male). The term "inside" is used to differentiate this type of sex from vaginal penetration, which is referred to as "outside."
