Because there are no set legal regulations about sex toy materials, you need to be very thorough in your pre-purchase research to make sure you buy a sex toy which is body safe and will last. Certain materials break down quicker than others, over time and through repeated use. This can make them uncomfortable, unreliable and in some cases, potentially harmful to use within your body.
Metal kegel balls - and in fact all metal sex toys - should be made from a good quality, body safe metal with a smooth surface. Metals used include steel, aluminium and even gold or silver. There are different quality levels of steel, in particular, so look for sex toys made from surgical grade stainless steel. Lower quality steel is mixed with other metals as an alloy, which is a cheaper material to use. The surfaces of lower quality metal sex toys can wear away over time and can expose a surface which is unsafe to use inside you.
Even if you’re sure that your metal kegel balls are made from a body safe metal such as surgical grade stainless steel or other, damage can still occur to the surface if you don’t look after them properly. Cleaning metal kegel balls as soon as possible after use will help to ensure that the surface isn’t exposed to any corrosive elements for long periods of time. For example, you shouldn’t clean them in a dishwasher or use jewellery cleaners on them as the chemicals involved could lead to surface damage.
Metal kegel balls, indeed all metal sex toys, should retain the shiny, unbroken and smooth surface they had when brand new. Any tarnishing beyond a slight dullness, or any corrosion and damage to the outer surface of the kegel balls indicates that it’s time to shop around for better quality metal kegel balls that you can trust to use inside you.
