Firstly, not all women’s vaginas are the same regardless of whatever condition the woman is in: had sex, not had sex, is a child, is not a child, had a child, had no children, is menstruating, is not menstruating, etc.
Secondly, being a virgin does not have any bearing on the tightness of the vagina, just like being a virgin has no bearing on the tightness of other muscles in the body. A vagina is a set of muscles under a mucous cover; these muscles can be trained. Their tone does not depend on the woman’s age or any other thing. (No, not all women become “loose” after giving birth, imagine that.)
Now you have the data to give the answer to yourself.
(Hint: the answer is “no one can tell you, it depends on a specific girl and the specific state of tone her muscles may have”.)
