I know this is a story, but doing any one of these things will send you to the hospital. Your bladder is on the other end of your urethra and if anything gets in there, you can end up with a horrible infection or in the hospital getting it surgically removed. Wax, ginger slivers, and non sterile liquids, you're just asking for health issues.
Medical grade stainless steel and high quality silicone with sterile water based lube is the safest way to make sure you don't end up in the ER.
