A delay spray is prepared by keeping enhanced sexual activity in mind. The chemical formulation of these sprays contains numbing and desensitizing agents like lidocaine and benzocaine. If they were to rub off on your partner, then the whole purpose of the product would get defeated. Women do not require an agent to prolong their climax time as they are naturally blessed with the same. If they were to be numbed down during sex, your effort of reducing the chances of premature ejaculation would just get tossed out of the window. Most of the sprays that are available in the market are absorbed within a few minutes of application. Because of being mild numbing agents with a local area effect, these sprays won’t get transferred to your partner.
