Re: Vaginal septum & sex
Unfortunately having a vaginal septum can lead to Dyspareunia or painful sexual intercourse, due to medical or psychological causes (medical in your case). The reason for this is because it's as if you have two completely different vaginal canals sharing the space of one.
The causes of dyspareunia are often reversible, even when long-standing, but self-perpetuating pain is a factor after the original cause has been removed. Extreme forms, in which the woman's pelvic floor musculature contracts involuntarily, is termed vaginismus.
In severe cases of a vaginal septum, where dyspareunia is caused and sex is painful, surgery can be performed to simply remove the septum, recovery is typically between 4-6 weeks. This will be something that you'll want to discuss with your doctor during a follow-up visit.
