Turn your STP into an erect penis with a silicone insert rod. To use, simply slide the silicone Erection Rod inside the funnel of your STP and you are ready to go! The erection rods are hand poured so light imperfections or bubbles may naturally occur in the pouring process.

Each model STP has a unique silicone rod shape for just the right fit.  Erection rods are designed for the following STP models:

STP (STAND TO PEE) | 1ST GENERATION - MEDIUM

STP (STAND TO PEE) DEVICE | 2ND GENERATION - SMALL

STP (STAND TO PEE) DEVICE | 2ND GENERATION - MEDIUM

STP (STAND TO PEE) DEVICE | 3RD GENERATION

STP (STAND TO PEE) DEVICE | TOMMY STP NOTE: Use rod with care and leave plenty of room from the top to prevent the rod from puncturing and/or tearing the softer front tip. 

STP (STAND TO PEE) DEVICE | 4.5" REALISTIC

Quick Tip: We recommend applying a water based lubricant to the silicone erection rod before insertion to reduce friction.
