Why does it itch down there after sex?

Many women will experience itching in their private parts after having sex after marriage. There are many reasons for itching in the private parts. Excluding gynecological diseases, the itching may be caused by allergy to semen or by the woman's own disease. Women should pay attention to private hygiene after sex and keep their private parts dry and clean.

Why does my vagina itch after sex?

One is an allergy to condoms (or external contraceptives): condoms are a chemical product, and a small number of people have an allergic reaction to them. Women experience itching in the vulva, congestion and erosion of the vaginal opening and vaginal walls, and a significant increase in secretions from the vulva and vagina.

Men experience unbearable itching on the glans penis, leading to local tingling, and even congestion, edema and erosion of the glans penis. In addition, some drugs (external contraceptive jelly, external contraceptive film, etc.) can also cause allergic reactions.

The second is semen allergy: male semen itself is an allergic substance. If the wife has an overly sensitive constitution, an allergic reaction is likely to occur. The main symptoms are itching of the vulva, sometimes with mild congestion and edema. A small number of people may experience chest tightness, palpitations, or systemic "wheals".

The third is leucorrhea allergy: leucorrhea is composed of cervical fluid mixed with some endometrial and fallopian tube exfoliated cells and vaginal secretions. During sexual intercourse, cervical fluid and vaginal secretions increase, and the amount of leucorrhea also increases. There are many antigenic substances in leucorrhea that can become allergens. If the husband has an allergic constitution, it will also cause an allergic reaction. The main symptoms are itching and discomfort in the glans penis, penis body or scrotum area. Vulvar swelling or the appearance of "wheals" are rare.

Fourth, secretions contaminate the vulva and cause sexual stimulation: During sexual intercourse, secretions from the sexual organs (leucorrhea, semen, menstrual blood, smegma, etc.) are contaminated on the vulva, then dry and adhere to the local skin and mucous membranes, causing itching and discomfort.

Fifth, vaginal infection: vaginitis caused by Trichomonas or fungi can also irritate the vulva and cause itching.
