It has been a month and a half since the circumcision and the thread has not completely come off, it is recommended not to have sex for the time being. After circumcision, if you have sex before the thread falls off, you may scratch the vaginal wall, and you are also prone to infection and incision tear. If it is an absorbable thread, you can use iodophor to wipe and disinfect it locally, wait for it to fall off by itself, and don’t masturbate or have sex before the thread falls off. Therefore, you can have sex appropriately when the thread falls off, but it is recommended not to have too much sex, because the wound is still in the recovery stage. In daily life, pay attention to keep the local clean and hygienic, don’t eat spicy and stimulating food, and avoid sitting for a long time. To summarize, if there is any discomfort after circumcision, you should consult a doctor in time.
