1. Frequently Smoking
Many men are addicted to smoking, with some going through an entire pack a day. They may smoke due to stress, sadness, or simply out of habit. However, this is a dangerous behavior that can harm not only themselves but also their wives.
2. Refusing to Use Protection During Intimacy
Some women turn to birth control pills as an alternative, believing it to be a safe solution. However, research from the University of Copenhagen (Denmark) shows that long-term use of hormonal contraceptives can increase a woman's risk of breast cancer by up to 38%. According to the New England Journal of Medicine, women who use daily pills, injections, or implants for under one year have a 9% increased risk, but if used continuously for 10 years, that risk can climb to 38%.
3. Demanding Intimacy During Menstruation
Sexual intercourse during menstruation can have serious health consequences for women. At this time, the uterine lining is still open, making it highly susceptible to bacterial contamination.
According to Dr. Trần Ly Hồng (First Affiliated Hospital of Fujian Medical University), engaging in intercourse during this sensitive period significantly increases the risk of infections and gynecological diseases. If left untreated, these conditions can develop into cervical cancer.
Therefore, during menstruation, if a husband or partner makes such demands, women should firmly refuse in order to protect their health.
