Pretty much yes!
The term 'social construct' does get thrown around a lot; strictly speaking, all the language, words and status we give to all things in society are social constructs. However, I feel like concept of virginity goes much further than that, and is a particularly dishonest and harmful construct.
Our genitals, just like other parts of the body, can change over time depending on what you do with them, be that vaginal stimulation or different types of exercise, but there is no universally measurable "before" and "after" of sexual intercourse, and yet the 'idea' of such a difference is used to surpress and control so many people with vulvas. It's quite an injustice!
We have a bunch of pieces on the topic because it always comes up and it seems popular culture won't get the memo.
