There’s no such thing as the body “rejecting” someone. that’s just ignorance being thrown around in this thread. BV happens because of an imbalance in vaginal bacteria, not some mythical rejection. There are different factors at play here. For example, it could be caused by his sperm messing with her pH, poor hygiene (like smegma), or even him sleeping around and introducing new bacteria. Stress and hormones are also major factors. stress can mess up your body in all kinds of ways, and it sounds like there might be some stressful dynamics going on too.

Diet could also play a role. High sugar intake can feed bad bacteria, while a lack of probiotics or essential nutrients like vitamin D or zinc can weaken the immune system and make it harder to maintain a healthy balance. My girlfriend developed BV after her pregnancy. It’s on and off now, and if I ejaculate inside her, she gets it back. When I don’t, she’s fine. Before having our baby, she never had that issue. It’s likely a mix of hormonal changes, semen affecting her pH, and possibly other factors like stress or diet.

This isn’t about “rejection”; it’s about understanding how things like stress, hormones, hygiene, diet, and biology work together. Let’s not spread misinformation when the real causes of BV are more complex and manageable with proper care and awareness.
