From my own experience I can say the following:
Pros: she can change when nothing changes for her. Such girls will not worry about the delay, and she will not think about the consequences that she may have in the future. Such girls will have wonderful and clean skin, because many girls from among active sex life have sores on their faces, and this is very bad. And as you know, many girls are always afraid to go to a gynecologist, if she is still at an early age and is no longer a virgin, then a virgin with pride and peace of mind to go to a gynecologist.

Cons: Many men, when they find out that a girl is a virgin, she can abandon her. There are those who are simply afraid of responsibility, because after a romantic night, the girl will need support. If a girl is deprived of virginity with her husband and after a while he began to her, then the girl may begin to reproach him for keeping her virginity for him all her life, and he does this to her, because it is mean and low on in relation to her. And such girls must remember that there is no need to keep themselves until old age, even if there is a serious relationship, it is more painful to lose their virginity at a later age.
