Well, authoritative and energetic handsome guys will answer-haha, just kidding, as if I am a big sports boy and have sex with my girlfriend-and often break records. The fact is that young men are actually more excited in this respect. Women should treat this matter with caution. You should know clearly. Men can be good to you because of this 10 times, or they can be scared because of this. This is not a human fault, it is a natural law, which can be explained from the perspective of evolution. I won't go into details here. I am not looking for objective reasons. Because of the role of the women's hall in women's twenties. Men are often fascinated by you. So don't put everything on men. Afraid it's bad for men. That's it, principle! Sex must have principles, such as four times a week, five times. You can only shoot 1 time at most a day. Run every day, be sure to drink soup. Do more exercise, don't sleep late and so on. Communicate with him, just like my wife-if I can't finish the task, I won't be allowed to get excited% ... once a day 1 time. I'm definitely more energetic than your boyfriend, but we can communicate together to reach the principle. Secondly, cooperate more in the process of doing it, knowing that you will be happy even if you pretend to be your boyfriend. Men are so stupid sometimes-because I can guarantee that your man will be obedient to you in terms of harmonious life. I know that some hardships are not easy for women, but you must believe that it is worthwhile to pay. A 20-year-old woman is the flower of the peak. If a man doesn't have a good companion at this time, he will regret it all his life. Harmony needs communication. Happiness belongs to two people.
