The film was originally to have been titled Sumisión (Submission), quite in keeping with the film's content, but it finally wound up with its present name (literally meaning "my pussy is the best"), which the director Ricardo Palacios hated.
The first film directed by Ricardo Palacios. It was made under the production management of José Luis Merino.
The original cast weren't present during the dubbing stage, which took place at Exa studios. Director Ricardo Palacios himself dubbed the character of the caretaker.
Due to the film's success, plans were made for another sex film (this time a comedy with political overtones) to be directed by Ricardo Palacios and again starring Lina Romay and Emilio Linder, but it failed to take off.
Lina Romay was cast by director Ricardo Palacios at an audition when he realized the other contenders were far more limited than she was for the type of hyper sexual role. He admitted later he could have chosen a cuter, daintier girl than Lina, but he was very happy with his choice, especially after they started filming. She was extremely uninhibited and willing to strip all her clothes off at a moments notice for any reason and fully throw herself into the sex scenes. He said she told him she was an unabashed exhibitionist who enjoyed being naked in front of others. Palacios said she didn't bother putting on a robe or leaving the set while the crew set up shots. She would hang around still naked and talk to the director and crew. She obviously loved the attention and the crew enjoyed giving it to her.
