Your family says they can smell it? So, we have folds down there where bacteria can get trapped. One thing you can do is take a small amount of antibacterial soap and put it on a cloth and wash in those folds. Your vagina is self cleaning. That shouldn't be washed out. If you have discharge that is thin and watery, possibly greyish in color, you may have bacterial vaginosis. This can happen even when not having sex. If you exercise or do sports, damp panties trapping the air can make the environment perfect for this happening. Antibiotics are used to treat this. A doctor swabs you and tests for it. The washing with antibacterial soap in those folds though may solve the problem. You can use probiotics (either pill form bought at the drug store or the smoothies they sell at grocery stores or yogurt) that helps make the ph balance in your vagina normalized, cut down on sugar, wear cotton underwear you change often, and consider an 'air out' at night by sleeping without underwear for a night or two. good luck
