How to deal with coldness properly?

Patient's question:

Patient: Male, 31 years old, previously in good health
Condition:
My husband has recently lost interest in sex and often goes without for three or four months at a time. Sometimes, he also performs reluctantly.

Doctor's answer:

Hello, if you have premature ejaculation, you can take herbal medicines such as Jin Suo Gu Jing Wan and Liu Wei Di Huang Wan for treatment, or combine with Western medicine therapy. Currently, selective serotonin reuptake inhibitors, tricyclic antidepressants, and local anesthetic drugs are used for primary or secondary premature ejaculation, each with different effects.
