Mamiya from Universe Tokyo here. A woman’s body is mysterious, and it can change depending on her menstrual cycle, emotions, and physical condition. Since this involves vaginal secretions, diet and immunity may also have an impact. If it continues for a long time, there may be something that needs to be addressed. I recommend getting a checkup and having the vaginal discharge examined. Trying various things based on guesswork may improve the situation temporarily, but you could ultimately be doing the wrong thing at its root. For a long-term relationship, men should also make an effort to understand the vaginal environment.

Maezawa from the CEO’s Office here to answer as well. Thank you for your question. There could be various factors, and I’m not an expert, so I can’t say exactly what’s causing it. However, it does seem that a man ejaculating inside can change the smell. Mac mentioned this before and has linked to it again, so I think you should buy the “Chuchu” product mentioned there. https://tclinic.jp/VitaminC.html

I’m Kazu, a male member. There are many possible explanations, but I suspect a major change in circumstances may be involved. That could mean living alone, having a new sexual partner, having sex without a condom, letting someone finish inside, or any number of other changes. Come to think of it, one woman told me she started to smell after letting someone finish inside, while another said that after contracting an STI and receiving treatment, she was no longer odorless. Again, there are many possibilities. Even she probably can’t identify the exact cause with certainty. I only mentioned the possibility of sex because the person asking didn’t bring it up in their question. It could be her diet, or stress. I usually speak frankly, so I would ask directly—but politely—whether she had any idea what might be causing it and what her recent sex life had been like.
