@CookieMonster OUCH! hand sanitiser is mostly rubbing alcohol.
Firstly it would be irritating to the sensitive skin of the genitals, secondly it would mess up the natural balance of bacteria in the vagina (likely causing an infection); and thirdly, it would be useless as a lubricant since it’s designed to be absorbed quickly.
Real lube is easy to find at supermarkets, chemists, online or at adult themed shops 🙂
