If you really like her, you should find a nice way to help her fix the problem. Maybe offer to shower together first. I believe you should be honest with people, but a subject so sensitive could hurt her feelings. Another thing is, it may not necessarily be her hygeine. It could be a bacteria infection, which is harmless to you except for the smell. I say that because if thats the case then she needs to probably see her Gyno and get a treated because if a woman has Bacterial Vaginosis or other infection, I dont care how much she bathes, the scent will stay hidden very shortly but it will keep coming back. You can google BV and see what the symptoms are. Just because she may have it dont mean shes dirty either. Lots of things can throw the balance off. Most of the time, an antibiotic is needed to clear it. It'll go away but come back if not properly treated. I dont see how any woman could deal with it. That shit smells bad. Lets hope its not an std or not her hygiene and she isn't just a dirty twat that don't know how to wash properly. If you not really into her, then move on but if you really like her, its worth letting her know because she may have gotten accustomed to it. Every pussy has its unigue scent, flavor but its not supposed to smell bad. Either the way the guy is supposed to like it.
