So i've been dating this girl for a few months now. I've been enjoying my time with her, she's smart, she's sweet, but I can't say I've been looking forward to the sex as much. Whenever I go down on her her vagina has this strange smell/taste I can't quite put my finger on (no pun intended). I guess the best way for me to describe it would be like tart/sour milk. Sometimes I get her juices on my boxer and it smells just like spoiled milk.
She seems really clean and always have wonderful scents on her body, but sometimes its difficult to have sex cause of this smell. Sometimes I could even smell it when we do doggy position.
I've never had this happen to me before so I'm not sure how to proceed or how to handle it. Any advice?
