Hi thanks for your question
I can understand your concers
Your married 5 months back and still you have not undergone successful intercourse
What is more important during sex is how much your relaxed.
If your fully reaxed vagina can provide enough lubrication for penetration and there is no need for artifial luberication
Second important thing is how much comfortable your with your partener.
If your comfortable with your partener andd relaxed ,don't have fear of pain during sexual intercourse, then there is no need for artificial lubrication.
However ther is no harm in using local application xylcaine jully for lubrication . xylocaine
provide lubrication as well as blunt the pain of first penetration
After few applications, you will not reqire xylocaine jully.
Hope i answered your question
