Obviously there is no pat answer to should we do it or not - before marriage.
I seriously doubt many younger folks would wait, for sexual compatibility is a big deal. And if it isn't a big deal, then once married it could very well turn out to be one. And I do believe these days its as big a deal for a woman, as it is for a man regardless of sexual orientation.
From what I've seen/heard, abstinence before marriage (here in America) is a pretty rare thing now adays - especially for young folks. Heck, most all I know of personally live together first.
Ideally, I wish folks got married, had sex, had children, loved each other and stayed together happily until "death do us part". But that just is such a rarity, its pitiful. Believe me, I know.
