rohini, if you are a male, then you are disgrace to human species.. if you are female, then you need to understand that your male should shower before banging you, or you going down on him. perhaps you should also realize how important it is for us to know that women are clean there. if you and yours want oral, then shower before you do that, if you are only doing a quicky like in the early morning or in a break from a party or work, then forget about the dirt there, just enjoy the plain quick sex. sex is the best thing as much as pot is... so, just relax and enjoy the fun.. don't worry about dirt there. it would be dirty anyways after you cum...
