Random Question TMI

Ladies please help!! I'm a very clean person so the smell bothers me but I don't know what to do to make it go away. I'm married so I am very active in sexual activities (one man) and we are ttc so of course he does in inside. And we all know it smells bad if we don't wash. Well I wash right after sex and sometimes early the next morning. The smell won't go away. I only do things naturally and use natural products as I don't like to put random things inside of me that may hard me or what not.
