What is the reason for normal sexual function but a lack of libido?

Patient's question:

Sexual function is normal, but both lack of "sexual desire" has been for a while... (had it for a year) Every time it's semi-soft and not hard, previously it could be very hard but couldn't get morning erections daily (occasionally there would be, but not hard) Every time when trying to self-pleasure, there's no sense of excitement after starting (using a sex toy), but it ends in about 1 minute each time (previously in normal condition it was also about 1 minute) ...What's wrong with the above issues? Why is there normal sexual function but a lack of sexual desire?

Doctor's answer:

In this case, if there are no organic diseases, it is generally related to mood and psychological adjustment. It is recommended to actively exercise, avoid smoking and drinking, maintain a regular schedule, and pay attention to eating more zinc and kidney-tonifying foods. Avoid unhealthy sexual habits. At the same time, pay attention to sexual restraint. For male patients with diseases, timely treatment can reduce the incidence. If not treated in time, it will affect health. Therefore, patients should take medication promptly and maintain a regular lifestyle in daily life to avoid prolonged sitting.
