Foul smelling discharge?

Well make sure you wash your dildo after and woman normally wash their vagina with either shower gel and soap but that's were they go wrong because woman have so many good bacteria in their vagina and when you wash with certain products the Bactria are trying to work so hard to get rid of what ever it is your using and it starts to smell fishy and also try and use KY jelly or some fort of lubricant and after use please wash but if the discharge only smells and its either yellow or green please see a doctor as you could have an infection!
