Hi, thanks for using healthcare magic
There is a condition called vaginismus
which involves spasm of the muscles in the vaginal wall. This spams limits sexual intercourse.
It can be caused by a number of different reasons.
Diagnosis is based on history and examination findings.
Treatment involves the resolving the causative. In some persons psychological counselling
may be necessary.
In addition to the counselling, probes are sometimes used to widen the passage.
I hope this helps
