This is a small sampling of articles regarding the risks associated with douching.
Unless your doctor SPECIFICALLY states you should douche...douching is a bad idea. I've spoken to my doctor about it and she told me NOT to douche.
As far as smell is concerned, all women smell down there. ALL of us. It is normal, and unless you have an infection, very natural. If I were you, I would rule any infections out by seeing a doctor, then explain to your boyfriend that oral sex is something you enjoy and would like for him to do with you. Good sex requires communication, and unless you explain your feelings to him, he'll never know how much this means to you. Good luck.
