Couples who are worried that sex during pregnancy will lead to pregnancy risks, or who have not found a soulful feeling during sex before pregnancy will choose to avoid sex during pregnancy, and so there are inexplicable episodes of bad moods in the wife that make the husband feel incomprehensible; the husband cannot resist the sexual urge to choose sex outside of marriage to solve problems and a series of life events that have a negative impact on intimacy. Many women with postpartum depression do not realize that abstinence during pregnancy has planted a time bomb for their misfortune. In fact, there is a lot of wrong knowledge about sex during pregnancy, here to clarify: 1, modern reproductive medicine has reached a consensus that sex is not a taboo for normal pregnancy The previous view that “the first and second trimesters of pregnancy should not have sex, and the middle trimester should also try to avoid sex” has been overturned by the modern field of reproductive medicine. The previous view that “sex is not allowed in the first and second trimesters and should be avoided in the middle trimester” has been disproved by the modern field of reproductive medicine. The latest consensus is that pregnancy is not a contraindication to sex, and there is no distinction between the first, middle and second trimesters. The reason is that the main reason for miscarriage in the first trimester is the poor quality of the embryo, which has nothing to do with sex; the main reason for miscarriage in the second trimester is pathological obstetric problems, such as placenta abruptio, placenta praevia, cervical canal relaxation, etc. Such pregnancy conditions are the main cause of miscarriage and preterm delivery, and should not be blamed on sex. Therefore, modern reproductive medicine for sex during pregnancy is this advice: as long as there is no bad pregnancy history; no pregnancy test suggests high pregnancy; no medical advice to avoid sex; no physical discomfort; and have a sexual desire, are able to have sex. 2, sex position during pregnancy is a precautionary In early pregnancy the body of pregnant women and no changes in shape, sex position is not taboo. Mid and late pregnancy, as the abdomen grows, the pregnant woman’s life in a variety of positions restricted feeling will become more and more obvious, sex position of course, should also be careful up. To avoid the frontal squeeze abdomen position and any penetration too deep and can hit the cervix of the position: such as the common male top missionary, kneeling back into the position, etc.. The woman-on-top position allows the lady to fully control the depth and rhythm of penetration, and the seated woman-on-top position is less physically demanding for the lady and is recommended. Side position sex is slower, shallow penetration depth, and side back entry is particularly suitable for the characteristics of sex during pregnancy – lingering and intimate but not intense. Of course, the choice of position also takes into account the issue of personal preference, specific experts can be consulted to find the most suitable for their own position. 3, pregnancy sex considerations (1) the body hormonal changes during pregnancy, pregnant women’s libido will occur very individualized changes, that can become very strong, can also become not strong, can also not change.

So, pay special attention to each other’s feelings and not just focus on the needs of the woman. Husbands should take care of their wives, but couples are equal, and wives should not be so superior, and it would be inappropriate to treat their husbands’ sexual needs with disregard. (3) Sexual life during pregnancy can be varied. If either spouse does not want to insert sexual intercourse, they can satisfy each other with hand or oral sex. However, the resistance of the vagina decreases during pregnancy, so use a condom during hand sex and do not stimulate the inside of the vagina during oral sex. (4) Since the vaginal resistance decreases during pregnancy, and since uterine infections must be strictly avoided, condoms must be used throughout sex during pregnancy. (5) Sex during pregnancy to meet the basic sexual needs, as well as to increase the sense of intimacy between each other, not to seek stimulating passionate sex as recommended.
