I appreciate your query
You might be experiencing mild friction due to irritation by the condom.
This is quite common with condom use.
You can easily remedy it by using some lubricant alongwith the condom prior to sexual intercourse.
( eg . Lubic gel ) etc.
You might use a local cream such as Onabet - B to ease the vaginal itching
Also, prelubricated and super thin condoms are available in various brands to reduce irritation, burning and friction.
If this does not cure it, and the vaginal irritation
persists or increases, please see a doctor for an examination and to rule out any infection.
Do not vigorously clean or rub your labia and private parts or use any medicated lotions or cleansers.
Mild warm water is the best for cleaning.
Keep yourself dry, avoid moisture, use cotton underpants.
Hope this helps.
