Urethral sounding, don’t knock it til you’ve tried it. It’s slowly and comfortably sliding a thin rod into a penis’ urethra for internal stimulation you may have never experienced. The three piece set of silicone Dockers are the perfect probes to slide right in with their varied widths starting with the thin 1/5” wide, then ¼” thin, with the thin at 1/3” wide. Shaped like slender beige penises and completely flexible, they’re perfect for first time use, especially if it’s just the tip.
