Yes! Many of the ingredients included in Provestra have a direct impact on vaginal lubrication -- increasing the speed at which you become "wet" as well as the overall volume of lubrication available during sex.
Lubrication is important because it has a direct impact on sensation AND desire!
The earlier you lubricate during an intimate encounter, the faster you begin to experience more intense sexual sensations -- and the more desire you feel "in the moment" for your partner.
It's an erotic cycle:
More Lubrication = Increased Sensation = Increased Desire
… Which then equals MORE lubrication, and so on.
So yes, a key focus in the formulation of Provestra was increasing women's lubrication early during a sexual encounter, helping you overcome the very common problem of vaginal dryness.
