I'm sorry to hear you're experiencing irritation and itching after intercourse. This can happen for several reasons, including:

• Vaginal infections such as yeast infections (candidiasis), which are common and can cause itching, irritation, and discharge a few days after intercourse.
• Allergic reactions or sensitivity to lubricants, condoms, soaps, or other products used during sex.
• Physical irritation from friction during intercourse.
• Bacterial vaginosis or other infections that may cause similar symptoms.

One common cause is a yeast infection, which can be treated with antifungal medications like clotrimazole gel. For example, a product called Candid-V Gel contains clotrimazole and is used to treat vaginal thrush (yeast infection). However, it should be used only under a doctor's guidance, especially if you are pregnant or breastfeeding.

Recommendations:

• Avoid using scented soaps, douches, or vaginal products that might irritate the area.
• Wear breathable cotton underwear and avoid tight clothing.
• Consider seeing a gynecologist for an accurate diagnosis and appropriate treatment.
• If symptoms worsen, persist, or are accompanied by unusual discharge or odor, seek medical advice promptly.
