Is it ok to use spit on a flesh-light?

Using saliva as a lubricant on a Fleshlight is generally not recommended because it can introduce bacteria and lead to infections. It's better to use a water-based or silicone-based lubricant specifically designed for use with sex toys, as these are safer and can enhance the experience. If you do choose to use spit, be sure to clean the Fleshlight thoroughly afterward to maintain hygiene.
