John V, there are several things this could be. What you need is to get the issue correctly diagnosed, and for this you need to see a Medical Professional, and you may require tests, or be sent to a Dermatologist.
The potential causes range from relatively simple, such as Vitiligo, to a permenant skin condition.
Go to a Regular / Family Doctor / GP or to any Walk-In Sexual Health Center …

looks like Lichen sclerosus or lichen simplex chronicus
