Sounding

A sterile rod into the urethra, slow, with lube — stop at the first sharp pain.

Why people do it

A rod in the urethra produces a sensation from a place with no other use, and the carefulness it demands is part of what people find compelling about it.

Smallest way in

Purpose-made sterile sounds, sterile lube, largest size that passes without force, and read a proper guide before the first attempt.

What to watch

Sterile, single-use lube and cleaned rods every time — a urinary infection is the usual outcome of doing this casually. Never force, never against sharp pain, and never anything not made for this. Blood or lasting pain means a doctor.

In the planner

1 different things carry this tag, and switching it off removes every one of them. The mildest of them sits at extreme.
