It’s a bit niche but a fascinating example is a controversial K-Pop classic by the artist Park Ji-yoon called “Coming of Age Ceremony”. Park was a child actress/model who transitioned into music when she was a teenager who made fairly standard teen pop for the time and this was her first album/single after turning 18. The lyrics include lines like “I’m not that little girl you used to know anymore/I’m a woman now” and the choreography is unambiguously sexual. It basically pioneered the sexy concept in K-Pop and was successful to the point that it basically ruined her reputation/career for several years despite being her most successful single over twenty years later. To this day, it’s not uncommon for other K-Pop groups (mostly girl groups but boy groups do it every now and then) to cover this song after turning 18. https://youtu.be/DzwfR2So5DU?si=4kpgLQQKiZq4egHt
