How to use a penis plug

Wash the plug thoroughly with warm water and mild soap before first use. Apply generous water-based lubricant to the steel tip and your urethra. Begin with slow, controlled movements, allowing your body to adjust to the sensation. Select the glans ring that fits comfortably around your penis head, then gently insert the tip into your urethra. Never force insertion; let your body guide the depth and pace.

Once inserted, wear the plug for short periods initially, gradually extending duration as your body adapts. The removable cum stopper allows you to manage fluid flow during wear. Explore different positions and movements to discover what intensifies sensation. When ready to remove, apply fresh lubricant and withdraw slowly using gentle, steady pressure. Afterward, clean the plug immediately with warm water and mild soap. Pairing urethral play with Penis Pouches can enhance comfort and containment during extended sessions.

Care and storage

Clean the FELIX Flexi Tube immediately after use with warm water and mild soap, paying special attention to the steel components. For deeper sanitation, boil in water for 5–10 minutes or use a toy-specific antibacterial cleaner. Dry completely with a soft cloth before storing in the included bag. Keep it away from direct sunlight and extreme heat. Store in a cool, dry location to preserve material integrity.

Mistress Athena's training notes

By Mistress Athena — professional dominant and kink educator, sole instructor behind BDSM Australia's library of training videos. Read her full bio →

The FELIX Flexi Tube's steel precision mirrors my own control. Watching a submissive's breath catch as cold metal enters their most sensitive flesh tells me everything about their readiness. My technique begins long before insertion—psychological preparation, eye contact, absolute command of the moment. The removable stopper becomes my tool for denial, for extending their vulnerability.

Insertion speed matters more than depth. Slow, deliberate movements keep them focused entirely on sensation and surrender. Steel's temperature contrast against warm tissue creates exquisite vulnerability. I observe trembling hands, dilated pupils, involuntary responses that reveal their true submission. Some require gentle introduction; others crave ruthless control. This device transforms trust into tangible sensation.

Duration builds psychological impact. Extended wear under my direction establishes complete power exchange. The cum-thru design means they remain aware of their own body's responses while unable to act on them. My submissives learn that pleasure exists only through my permission. The FELIX Flexi Tube becomes less about physical sensation and more about absolute obedience.
