Thank you so much, both your replies has helped alot ....yes I did mean Vaginal Stenosis.
And some hormone cream, to relax and moisten the vaginal walls. Talk to your doctor.
You don't need your cervix to be open for intercourse (in fact, the cervix shouldn't be open unless you're giving birth). Do you mean you have vaginal stenosis? If that's the case, then you might be able to use a vaginal dilator to slowly stretch things out again.
