im bi and currently have 4 sharpies in my ass atm. all of which are bottom side in not lid side. i use the lid clip as a way of making sure i dont put anything in too far(like a grappling hook) so i know i can keep them in as long as i want and not worry about losing anything. i once went to school with 2 in me once. my gf never suspected a thing.
