Hello dear
I understand your concern
Do not worry.
I have seen lots of case in my practice in which just entry of glans/tip of penis cause
pregnancy.
Other advises that will help you:
You can take following advises:
Insert penis very slowly, once you feel pain then stop more insertion and divert mind toward other thing, do some other movement.
In starting day you enjoy sex by just inserting glans of penis and gradually increase length of penis insertion.
Breath during mouth at the time of insertion. It will relax anal and vaginal sphincter.
Use water based lubricant like K-Y gel during intercourse.
It make entry of penis very smooth and painless.
Also rule out any vaginal / urinary infection, pelvic inflammatory disorder by consulting gynecologist is problem remain persist.
Other things that will use if problem persists:
Couple of
psychological counselling is given along with
pelvic floor training by experts.
Medications like
Botox and anxiolytic can be use at last.
Avoid
stress, take healthy diet, drink plenty of water, maintain proper pelvic hygiene and do regular exercise.
