No matter whether the other person asks you or not, I feel that this kind of thing is up to you. Now it's popular for everyone to start fitness. Whether it is a boy or a girl, a good figure is definitely a must. Not that you exercise to please each other, but to satisfy yourself, which will make you more confident.
46-year-old Niu Li can still have a vest line, which is really admirable, because many people are not so strict with their body management after 35 years old. It doesn't seem to matter about the requirements of life. I just feel that there will be nothing to look forward to after marriage. General fitness enthusiasts are mostly men, not too many girls. Maybe when they were young, they would practice the vest line and so on, but when they get married and have children, you can clearly feel that most people don't pay attention to this problem.
I wish I was Niu Li's age, not to mention having a vest line, but I must stay healthy. After all, this is the basis for you to have everything else, which is very important. I never care much about what others think, especially my partner. For me, no matter what decision I make, it is because of my inner call.
Even if the other person doesn't ask you to do this, you can still keep in good shape. Although you are husband and wife, you don't have to please him all the time.
