How hard is it to marry a virgin?

I don’t really care about a women’s “purity” but I am concerned about the link between divorce rate and pre marital sex. I’ve heard that when abstaining from sex before marriage divorce is decreased. I’m an 18M and so far I plan on abstinence before marriage but how realistic is that?

Do most girls 1. expect sex from boyfriend before marriage and 2. Will most likely have had multiple sexual partners?
