Can sperm cause unusual feminine odor?

Unfortunately ,yes. Even after you wash and clean, you can have a lasting smell. There is a chance that you have a blatter infection if it's kind of fishy. And in that case you'll take antibiotics for a few weeks. (Remember birth control doesn't work with antibiotics). But if it doesn't go away that can be a normal result of mixing acidic and basic solutions (your and his fluids). It might just kind of always be an issue. The only thing you can do is, wash yourself out afterwards and also eat things like yogurt (foods with natural pro-biotics). Good luck.
