Doctor's answer:

1, Some women have a sense of uncleanliness in their own private parts and fear polluting their partner.
2, During puberty, certain abnormalities in physical appearance are feared to be discovered, leading to feelings of inferiority.
3, After romantic or marital failures, they believe they have been deceived and may even develop a sense of retaliation against men.
4, Concerns about pregnancy, miscarriage, or sexually transmitted diseases may cause them to avoid sexual contact.
5, Pain or discomfort during sexual intercourse makes them afraid of having sex.
6, The woman views sexual life merely as a duty of a wife, not as a natural and psychological need like eating. If combined with a lack of sexual knowledge, resulting in insufficient sexual skills, monotonous ways, or even sexual climax disorders, sexual life becomes unenjoyable.
7, Unrealistic expectations of a partner, discovering that the husband in reality is far from the ideal spouse they had imagined before marriage, and unwilling to face or adapt to reality.
8, The husband lacks sexual appeal or has sexual dysfunction.
9, After giving birth, changes in body shape may make them feel they have lost their attractiveness to the opposite sex, or they may focus too much attention on their child, or excessive household chores may diminish their former passion for sex.
10, Some acute or chronic illnesses and the side effects of their treatment drugs can reduce sexual interest, or they may suppress sexual desire due to concerns that sexual activity may worsen the illness or harm their health.
11, Work stress, fatigue, alcoholism, or excessive mental pressure due to certain events may lead to a decline in sexual desire.
