Can Zestra be harmful to the vagina?
Zestra was designed to be applied onto the clitoris and labia (vaginal lips) before or during foreplay. Zestra can be used during vaginal sex, manual stimulation and masturbation. While Zestra is not harmful to the vagina in any way, we recommend that you only apply it to the outside of the vagina, as that is all that is needed to experience the Zestra Rushâ„¢.
