Question:
I have itchiness in my external genital since I was a kid and up to now, usually I feel more itchy when I have my period and wear sanitary napkin.
Is it possible I have STD? If not why do I experience it? I hope you could help me with this problem.

Answer:
The condition you are suffering from is known as pruritus vulva or itching vulva. This is a common skin condition of the vulva or the female external genitalia which occur whenever the skin is dry or exposed to irritation. When you are having your period your female hormone estrogen is very low and this can reduce production of natural moisture of the vulva skin and cause dryness. Using the pad which probably might contain some preparation can cause some irritation and itchiness. So also the content of the menstrual flow that can also irritate the external skin. I would suggest that you apply some moisturizer (like the Her Genicare Cream) to your vulva every time before you put the pad or after bath. The moisturizer can make the skin become supple and soft and will reduce dryness and thus no itching. In addition you may also want to try using the ESP Her V-Exclusive wash which being a 100% natural wash can help your condition. Sometime itchiness of the vulva can be caused by yeast infection. It is common for women to get this infection in the vagina through contamination from the anus or the urethra and when the discharge from the vagina is exposed to the vulva skin, the skin become infected, inflamed and itches. You can also get yeast infection from your sexual partner. Then this transmission is through sexual intercourse and known as Sexually Transmitted Disease. If the itchiness persists even after using the moisturizer, then you have to see a doctor. Preferably a skin doctor.
