Use baby powder after toweling off from the shower.
But whatever you do, DO NOT use deodorant/anti-perspirant! I knew a man who did this years ago -- and believe me, the smell you have is natural. What the additives do to a woman's tongue is NOT.
In addition to using baby powder, I also recommend that you air out your "doings" as often as you can. Get them out in the breeze, and maybe in some sunlight.
But don't be too sensitive about it. Naturally, people have much sharper smells than most in the sex industry believe. I've had many men ask me why amateur women have a sharper fishier odour than pros -- the answer is because they're more natural. We pros tend to wash away much of our natural environment. It's there to protect you, so have some respect for it.
