###Human: Does vaginal itching after sex indicate STD? ###Assistant: Hello. It may be normal, but I cannot deny from STD (sexually transmitted disease), and it may be herpes and vaginitis too. 1. Apply Betnovate-N locally up to deep in the vagina, after proper wash two times a day till required. 2. Ciplox TZ (Ciprofloxacin, Tinidazole) two times a day after food for three days. 3. Candid veginal tablet at night for six nights.It will be fine. And it means you believe in polygamy, which is one day become dangerous. Be loyal, and you can use her ten times a day. So she will remain healthy so as you. If she has vaginitis, you also can get the infection.
