OSEX BUG Mod (The Elder Scrolls 5: Skyrim)

In short, I did everything, but when the characters start having sex, the main character just flies into the air or under the textures and it does not stop, I tried everything except deleting the mod files or correcting them, installed both manually and with a nexus, there is no difference, I generally keep quiet about FNIS when I update everything, then all my characters are motionless.
