Pelvic floor strength directly affects sensation and control during intimacy. These glass eggs deliver weighted resistance training while offering smooth, temperature-responsive stimulation that builds muscle awareness and intensifies pleasure over time.
Crystal Premium Glass Eggs are precision-engineered borosilicate glass weights designed for internal pelvic floor training and sensory play. Each egg measures 1.75 inches long with a 1-inch diameter, sized for comfortable insertion while delivering targeted resistance. The transparent glass allows you to see the craftsmanship while enabling temperature play—warm or cool the eggs in water before use for added sensation.
These eggs stand apart through their body-safe material and dual purpose: strengthening pelvic muscles while providing intense sensory feedback during intimate moments. Unlike silicone or plastic alternatives, borosilicate glass is non-porous, hypoallergenic, and incredibly durable. See the full BDSM Australia range of Glass Sex Toys for other premium options.
Before first use, wash the eggs thoroughly with mild soap and warm water. Apply water-based lubricant generously to the eggs and your vaginal opening to ensure smooth, comfortable insertion. Gently introduce one or both eggs, allowing your pelvic muscles to naturally grip and hold them in place. Begin with short sessions—5 to 10 minutes—and gradually increase duration as your muscle control improves.
Once inserted, contract and release your pelvic floor muscles in controlled patterns, holding each contraction for a few seconds. This weighted resistance builds strength while creating intense sensory feedback. You can explore temperature play by warming or cooling the eggs in water beforehand. For advanced training, combine these eggs with Rock Candy Toys to vary your pelvic floor routine and discover new sensations.
Wash the eggs with mild antibacterial soap and warm water after each use, then dry completely. To sterilize, boil them in water for 3–5 minutes between sessions. Store the eggs in the provided silk bag away from direct sunlight and extreme temperatures. Never use silicone-based lubricants, as they can damage the glass surface over time.
Pelvic floor training enhances sensation, supports sexual function, and builds confidence in your body. Understanding the connection between muscle strength and pleasure deepens your intimate experience. Read more about strengthening this connection in our guide on Romantic Couples Sex Toy.
These glass eggs are precision tools for control. My submissives wear them during daily tasks, experiencing constant awareness of my dominance through their own muscle tension. Each contraction becomes a moment of surrender, each release a breath of relief I permit. The transparency lets me observe their discipline, turning intimate training into measurable obedience.
Progressive training begins with brief sessions and expands over weeks. My submissives perform assigned tasks—walking, serving, kneeling—while maintaining perfect placement. Success earns reward; failure brings consequences. The weight creates psychological submission alongside physical strengthening, transforming simple exercises into scenes of power exchange.
Temperature play adds another layer of control. Warming the eggs intensifies sensation; cooling them sharpens focus. My advanced submissives experience both, their bodies responding to every variation I introduce. Muscular mastery becomes mental surrender, and that transformation is where true dominance lives.
