The term "asexualizing" means to make something or someone asexual, which is the opposite of sexual. Therefore, the antonyms for asexualizing would be "sexualizing," "romanticizing," or "eroticizing." These words describe the act of adding sexual or romantic aspects to something or someone, in contrast to asexualizing, which removes those aspects. For example, while asexualizing a character in a book might remove any hint of romantic or sexual attraction, sexualizing that same character would emphasize it. Similarly, asexualizing a relationship might mean making it platonic, while romanticizing it would add the element of love and intimacy between the partners.
