Oh, that's all right. If I can help you, what about 100 points, hehe.
I have also studied this problem, read relevant materials and downloaded relevant pictures, which can give you a general explanation of your doubts.
As several friends have said before, it is possible that the hymen is broken due to strenuous exercise, which is normal and common without its knowledge. First of all, the hymen varies from person to person. Its function is to prevent external bacteria from entering the uterus from the vagina, but women are all menstruating, so there will be a hole, even a hole (people call it a "barren woman"). When menstruation comes, menstrual blood can flow out of the hole. Some people are thinner, less elastic and easy to break. Some people are thick and elastic and are not easy to break. This kind may not be broken when you are nervous for the first time or the environment is not very suitable at that time, and it may not be broken when you enter again. This will happen. There is also a kind of development in the mother's body, because the mother's own situation has changed, or some other external reasons, resulting in imperfect development and no hymen. There are not a few such people now, but this imperfection does not affect health, that is to say, it is dispensable. From this point of view, whether you are a virgin or not, the simple hymen represents nothing and can't explain anything. Those little boys who have virgin plots should also be clear-headed. Don't miss your girlfriend because of this seemingly crucial thing, which will affect your true feelings and real happiness.
Having said that, I also want to talk about related issues. Boys with virgin plots should not be naive enough to think that their girlfriends are virgins only when they see red. All wet. You know, technology is so developed now, from wigs to artificial limbs. What's more, a small hymen, something that makes you feel "proud" at a time, costs tens of dollars, which can completely repair a hymen. You can watch it as many times as you want.
So you don't have to worry about this problem.
