The vagina has a very delicate balance, and it's self cleaning. Douching will frequently bring on infection. No one should be douching. Honestly, there's nothing dirty in there. Only the outside area should be washed. If you are one of the small minority of men who don't like the natural odor of a clean vagina, then don't get that close to it. But I think it's a matter of personal chemistry. Some people smell wrong to me no matter what (not because they are dirty or something) , other people smell delicious even after the gym.
