After perianal abscess surgery, you generally need to wait until the surgical incision is completely healed before you can have sex, mostly in about 2-4 weeks after surgery. After perianal abscess surgery, the healing time of the incision is not fixed and is related to the mode of surgery and the size of the surgical trauma, as follows: 1. For some low perianal abscesses, if incision and drainage is performed alone, the recovery time after surgery is relatively fast, and the incision will generally be completely healed in 2-3 weeks after surgery, and sex life can be performed. For patients who have undergone incision and drainage, most of them will develop into anal Lou after the operation and need a second operation to be completely cured. 2. For patients who have undergone one-time radical treatment of perianal abscess, the operation is relatively traumatic because the internal opening needs to be cut open during the operation, so the healing time after the operation is relatively long, which may take 3-4 weeks or even more.
