It is normal for sexual desire to decrease with age. But according to your description, it's because you didn't have a good rest and your body was overdrawn.

To solve this problem, we must start from several aspects:

Take a rest, both physically and mentally.

Exercise: You can go to the park to see how the old people exercise. Never go to the gym to exercise your muscles.

Diet: Eat more foods that benefit qi and kidney.

Chinese medicine: by massage, moxibustion, acupuncture, medicine tonic and other methods, qi and kidney are replenished, and meridians are dredged. Massage should go to those regular meridian massage shops. Press it if it hurts, even if it hurts. Keep walking every few days until it doesn't hurt

Don't lead an irregular life after you recuperate. Can't make money. Don't spend money to make money.
