What is the technique of picking yang and nourishing yin in youth?

According to the ancient view of "collecting yang to replenish yin", the specific methods are as follows:

Choose a strong, grumpy, young but not necessarily handsome man as the object of Yang picking, because such a man is considered to have the most nourishing effect.

2. Be sure to let men reach orgasm during sexual intercourse, because men secrete the most yang essence at orgasm.

3. Try to extend the mating time so as to collect more semen.

4. You should have sex with multiple men, even as many as possible, because repeated intercourse with the same person weakens the nourishing effect of yang essence.

5. Men should endure the essence without shooting the room rate, and at the same time adopt the method of guidance and persuasion to "replenish essence and brain".
