1, the zippers of men's trousers are all in the front. If there are no underwear to stop them, they will be easily caught by their younger brothers. Even if I didn't get caught at that time, I was lucky. When I was running or exercising vigorously, I would get red by my zipper.

2, wearing underwear has a binding effect on the younger brother, tightly wrapped it, has a shaping effect, and can improve personal image;

3, wearing underwear will be more hygienic, no matter after defecation, some residues will not directly get on the pants. In this case, it is good to change underwear every day and reduce the number of washing clothes;

4, pants generally have pants seams, if you don't wear underwear, pants seams sometimes get stuck in the anus, which is particularly uncomfortable;

In case the zipper of trousers is broken one day, it will not be scolded by passers-by, which saves a lot of trouble.

It is said that the ancients did not wear underwear. In the past, most men wore robes, and their clothes were very fat. Now that the material conditions are good, everyone is becoming more and more particular. Not only will you wear underwear, but you will even wear good and expensive underwear, ranging from a few dollars to hundreds. In short, underwear ensures the quality of pure cotton, breathable and comfortable, not too extravagant. Of course, if you are rich, you should buy expensive ones. After all, expensive things must have their reasons.

I remember a joke. I heard from my husband that my buddy never wears underwear. One day, he was in a hurry to go to the toilet. As a result, the zipper was directly caught by the foreskin. The more anxious he is, the more he can't get it off. Finally, he pulled for a long time and finally broke the zipper before separating them. The toilet is open, but what should I do when I go out? Finally, Sheng Sheng waited in the toilet for two hours, waiting for his friend to send him pants. Therefore, in order to avoid such incidents, everyone still has to wear underwear.
