Bacteria thrive in the moist, dark environment and can cause odor. You may want to try using the no rinse hand cleansers. Use it only in the fold of the skin near the labia. Do not use in the vagina or labia minora (inner labia). You can put a small amount of antiperspirant on your finger and apply it to the fold of the skin near the labia majora
(outer labia) and the skin fold of the thigh. This will eliminate the sweating and prevent the odor.

Thanks I will try that. I hope it works.

I hope this works for you! It works for me.

I am 47. I have the same problem. It only started happening a few years ago. The smell is bad after sports. I am wondering if it is sweat or if it is urine and I need to start doing some Kegel exercises!
