Sex outside of marriage is damaging to everyone. It hardens the heart, encourages people to see others as mere machines for their gratification, reduces the ability to have lifelong faithful marriage, and more.
To have sex before one is of marriageable age is particularly harmful. And no, I’m not going to find statistics.
I do think the modern emphasis on putting off marriage is a bad thing. It is not easy for most young people to remain celibate or chaste througout their 20s. Easier for some and harder for others, everyone is different. Feminism has encouraged women to go to college for years, get a career, try out a whole bunch of men (or women) etc before even thinking of marriage. In fact, feminism has compared marriage to slavery, bondage and rape!
So feminism is greatly to blame for the mess of extra-marital sex that is breaking down society.

I was going to avoid any more posts on this thread (time constraints) but you raised a point I had debated but not mentioned, albeit from a different perspective.
Assume that a female virgin’s first sex partner shapes her in obvious and subtle ways. True, as I “knew” quite a number of such females.
Indeed, an argument can be made that a virgin female in many ways imprints on her first ‘lover’ (term used loosely), somewhat as a duckling, emerging from the egg, imprints on the first moving thing it sees.
In behavioral terms, the pair bond formation capability of a virgin human female at its maximum during her first sexual relationship.
Additionally, one may also say that multiple, unsuccessful pairings diminish strength and duration of pair bond formation.
Liberals and divorce lawyers adore the sexual revolution. Lots of income for them!
Knowing the above, I find it interesting that Judeo-Christianity bases its marriage ideal upon a virgin female.
Even the Ancient World valued virgin wives.
