"Box Theory" by Tinx: A Guide to Sex with a New Partner.

TikTok influencer Tinx has introduced her "box theory" in her new book, "The Shift: Change Your Perspective, Not Yourself," to help people navigate the dating world. The theory suggests that when a guy meets a girl in a romantic setting, he will put her into one of three boxes: he wants to date her, he wants to sleep with her, or he wants nothing to do with her. Tinx advises people to act how they want in the moment and not to manipulate their way into dating someone. The book's target audience is women, but the advice remains helpful regardless of gender identity or sexual orientation.
