Friction does not make vulvas, penises, or anuses happy. You need lube to make anal, toy, and hand play comfortable and pleasurable.
Anuses and penises do not self-lubricate the way a vagina does. Personal lubricants decrease friction from penises, hands, or sex toys. It’s kind of twisted that there is still a social taboo against using something that is literally designed to make sex better. Let’s get one thing straight: There is nothing wrong with using lube. Sex toys need lube to work their orgasmic magic to their fullest extent. In fact, they’re designed to go together. Sex toys and lube are what the woo-woo among us would call “Twin Flames.” They fit together perfectly. This is especially true when using sex toys.
