I am 22 years old and I have a active sex life.. It is almost 2 months that I notice my white mens is having a bad odor.. and I think the amount of that is not usual. What do you think is this?

What do you mean by "white mens"? Are you talking about normal vaginal discharge?

If there is odor involved, and an excessive amount, it sounds like a yeast infection. But we can't diagnose online. You'll have to see your doctor for an accurate diagnosis.
