Hello dear
I understand your concern
Penetration upto vaginal intoitus/entrance is sufficient to become
pregnancy.
But more the deeper penetration, more chance of pregnancy.
Penetration does not cause pain every time.
Once penis enter into the vagina easily then chance of the pain is less.
Pain could be due to:
Vaginal dryness,
vaginal infection, insufficient arousal,
hormonal imbalance, stress or anxiety, emotional upset.
I would suggest to consult the gynecologist if you have
pain during intercourse if you will face the pain.
Take following advises:
Use K-Y water based lubrication gel
use vaginal moisturizing agents like VAGISIL after bathing
Spend more time in the fore play before the sex
Enter the penis very slowly and then tell the partner to go forward till you do not feel the pain.
Maintain proper pelvic hygiene
Do regualr exercise like pelvic exercise, walking.
Take healthy diet and drink plenty of water.
Hope this may help you
