If you are in good spirits during a cold, you can generally have intercourse; however, if you are in poor spirits or have the flu, intercourse is not recommended. If you are in the middle of a cold, you are in good spirits and do not have a fever or other symptoms, you can have intercourse normally. Generally, it will not affect the normal course of the flu, and will not cause other diseases, so there is no need to worry too much. However, if the mental state is poor, or for the flu, it is not recommended to have intercourse. On the one hand, it may aggravate the symptomatic manifestations and cause the mental state to continue to deteriorate; on the other hand, it may transmit the flu to your partner and cause the flu to spread. It is recommended to consult a doctor and decide whether or not to have intercourse after consulting the doctor’s opinion, subject to the doctor’s opinion.
