The Non-hdt Navel Piercings and the RCB Meshes are separate addons and they can be used together, just download the one you want and overwrite (or load after) the main file.
That's why i made an extra set of all the nipple rings and navel piercings that use the normal high poly meshes. They have a '(No HDT)' attached to them in-game and will be properly positioned, so you can use them with the normal body (or a skimpy armor D). If you use the standard piercings with a non-hdt body or armor it won't be positioned right. All of them are set to use the hdt body and will jiggle with it (like in the GIF =D). Pretty much everything from the original mods: 10 Nipple Rings (5 Golden +5 Silver), about 40 navel piercings and 30 Prince Albert Piercings. HDT BBB Bounce for SAM (more about that below).Since the authors explicitly stated that their assets could be used, i decided to make this, but all the credits for the original work should go to them. This is a merged and refitted version of three LE mods: SOS - Mens Nipple Rings for Schlongs of Skyrim Body and Navel Piercings for Men and Adult Accessories for SAM. Note: I didn't create any of these textures or meshes.
