As the saying goes, women's hearts, autumn clouds, can be said to change, unpredictable, but also make suitors unable to start. But recently, a new study released by Indiana University brings good news for men: women are more likely to fall in love during menstruation.
The researchers tested 12 single women aged 23 to 28. First, their menstrual cycles were recorded and then tested with a special FMRI scanner. Finally, each woman was asked to browse 256 photos of men. The computer will first process these photos to highlight the masculine characteristics of each photo. In addition, the researchers told the subjects about the men's love history and asked them to pick out who they were willing to date.
The results showed that when women saw the faces of men with more romantic experience, the brain cells in the brain that manage decision-making and self-reward systems were much less active than those who had less romantic experience. Moreover, during or near menstruation

In addition, the activity of the brain's self-reward system triggers activity in other areas, such as the system that responds to drugs and alcohol. "this means that women have less control over themselves during menstruation and are more likely to be gluttonous, alcoholic or try adventurous activities." The researchers say.
Menstrual sex is very harmful to women.
Many young people know little about why they can't have sex during their menstruation, and they can't control their emotional impulses, so there are many people who break into the "forbidden zone" repeatedly. They think that having sex during menstruation can also be used for contraception, but they don't know that it not only saves trouble, but also consumes women's health.
The high incidence of endometritis, salpingitis, endometriosis and even infertility in women has a lot to do with unclean sex during menstruation.
We all know that normal women's genitals have multiple defense barriers: the first one is in the vagina. There is Lactobacillus, which produces lactic acid and maintains the acidic environment of the vagina, making the invasive pathogens untenable and unable to reproduce. The second line of defense is in the cervix. There is a mucus plug, which acts like a bottle stopper to prevent pathogenic bacteria from entering the uterine cavity. The third line of defense is in the endometrium of the uterine cavity, which has many wrinkles to prevent bacteria from entering the fallopian tube; menstruation
big black ass , endometrial exfoliation, and adherent bacteria are also "washed out" of the uterine cavity.
The above three lines of defense will be temporarily withdrawn during menstruation. Endometrial peeling is backward, leaving not only a huge wound, the cervical mucus plug is replaced by menstrual blood flow, at the same time, the acidic environment of the vagina is also replaced by the neutrality of menstrual blood. This is the time when women's resistance is weakest.
Therefore, if the couple share a room during the menstrual period, the pathogenic bacteria brought to the vagina by the penis will multiply in large numbers. These disease-causing "group" bacteria then swarmed upward, through the cervix, into the uterine cavity, and gathered on the wound in the uterine cavity. These pathogenic bacteria or adhere to the sperm surface into the fallopian tube, or because of the negative pressure caused by sex and be "inhaled" fallopian tube, it may cause salpingitis, so that its swelling

The serious consequence is that after the fallopian tube is blocked, the sperm cannot pass through the blocked site, and the eggs waiting here cannot be fertilized, thus infertility is formed. Sometimes the fallopian tube is blocked slightly, and the sperm can squeeze through the slit to reach the outer segment of the fallopian tube to fertilize the egg, but the fertilized egg, which is more than ten times larger than the sperm, cannot enter the uterine cavity through the slit, so it can only be planted in the fallopian tube on the spot, resulting in ectopic pregnancy.
There are five key points to be cautious about your menstrual sex life.
1. Try not to choose the first two days when the amount of menstrual bleeding is large.
2. The man should clean his genitals beforehand.
3. When having sex, the man should use a condom, move gently and shorten the time as much as possible.
4. After the event, the woman should immediately rinse the vulva with clean water.
5, although generally speaking, menstrual sex will not get pregnant, but from a health point of view
dildo masturbation , it is better to use condoms.
