Soundocking is a sexual practice combining elements of sounding and docking, in which both participants insert a metal rod into their urethras to establish a direct physical connection. (Optional practice) In this context, variations in
the distance or movement between the partners can cause the rod to vibrate,
potentially producing sounds at different frequencies that may be perceived as musical notes. This
experimental practice is undertaken consensually and requires strict adherence to hygiene and safety protocols due to its inherent risks.
