Do you smell like that to other people or are you the only one that smells it? Call your dr. to make sure you do not have an internal infection. Are your teeth good?
Not sure,maybe it is in your undergarments.
What medications do you take, and or what drugs do you do?
I am not accusing you of anything, I don't know you, but I am asking this for a reason.
Also, what is your diet mostly?
