Why does vaginal itching occur after sex?

When you are in love, having a passionate time with your husband should be a very comfortable and pleasant thing. However, some women always have some uncomfortable symptoms after passion, such as vaginal itching, vulva itching, etc. Over time, women will be afraid to be intimate with their husbands. So why do women experience this symptom after sex? And is there any way to prevent it?

1. Vaginitis

If a woman suffers from trichomoniasis or candidal vaginitis, the increased stimulation during sexual intercourse may cause itching of the vulva.

2. Semen allergy

Semen allergy is one of the important reasons for vaginal itching in women after sexual intercourse. The reason for semen allergy is that in addition to sperm, male semen also contains a variety of antigenic substances. If a woman has an allergic constitution, she will have a series of allergic reactions after sexual intercourse. Milder symptoms include itching of the vulva, congestion of the labia and vaginal opening, and urticaria-like skin on the labia. In severe cases, there may even be systemic reactions, such as chest tightness, difficulty breathing, facial flushing, and large areas of urticaria-like skin.

3. Allergy to condoms and topical contraceptive drugs

Condoms and topical contraceptives are both chemical products. Some people may have allergic reactions to condoms or topical contraceptives. —Generally, women experience itching in the vulva, congestion of the vaginal opening and vaginal walls, and a significant increase in vaginal secretions. Men may experience itching on the glans penis, and in severe cases, the glans penis may even become congested, edematous, and eroded.

4. Leucorrhea allergy

When women are sexually excited, their vaginal discharge increases. The vaginal discharge contains many antigenic substances. If the husband has an allergic constitution, it will cause an allergic reaction, and the symptoms are similar to those of allergic reactions to condoms and topical contraceptives.

Vaginal itching after sex is mostly caused by allergies, except for vaginitis. If it is vaginitis, this symptom will no longer occur after active treatment and recovery. If it is an allergy, the first thing to do is to find the allergens and avoid contact with them, or undergo desensitization treatment to prevent the occurrence of vaginal itching.
