Sensilube Lubricant: Some customers asked us what the best lubricant is to use with a fleshlight or Sexinacan. So we decided to give those customers the opportunity to test 11 different Lubricants and ask for their preference. This resulted in a unanimous nr 1 lubricant: Sensilube. Sensilube is a watery liquid, it won't stick and is very easy to clean from your insert. It's odourless and Crystal clear.
