Sex is possible after septum surgery, but can be performed one month after the surgery. Although having sex is not directly related to septum surgery, part of the cartilage or bone tissue is removed during septum surgery, which reduces its support. Strenuous exercise during intercourse and accelerated blood circulation may cause local congestion and affect wound healing, so it is recommended to have sex after one month when the wound has fully recovered. At the same time, avoid nasal collision during intercourse. In addition, due to the existence of wounds after septum surgery, it is recommended not to perform strenuous exercise, press on the nose or blow the nose forcefully for a period of time after the surgery, so as to avoid nasal bleeding or septum hematoma and other situations. At the same time, pay attention to rest, regular checkups, and strengthen the nasal dressing.
