At the beginning of X-sex, the man tries to keep calm and slow, and makes full use of the woman's loose sexual feelings, supplemented by caressing, so that the woman gradually concentrates her sexiness on the sexual organs and promotes her climax to come earlier. When the man feels that he has a strong desire to ejaculate and it is difficult to control it, he can rest for a while to inhibit the occurrence of ejaculation. Stop for a moment and then continue, which can avoid habitual premature ejaculation. I have used a very effective method, which can be extended for more than 20 minutes without drugs, that is, doing special training for 15 minutes every day. The training method can be referred to, xiaoren delayed training, (xiaoren Xiaoren) Baidu.
