Yes, single women would live with their families until they eventually got married. So their families could watch and keep them safe from predatory men who just wanted to use them for sex.
Yes, young men were eager to leave to house not that long ago because they ... WANTED TO HAVE SEX! and their ability to do so was being constrained by remaining at home.
Neither of these situations apply anymore. The vast majority of parents dont guard their daughters virtue anymore and may in fact encourage them to sexually experiment.
And boys don't feel like living at home keeps them from having sex because their parents let them use their rooms like hotel rooms and dont care if girls sleep over ect.
I can't say that maybe the kids tried it. But I know none of my friends would willingly allow that. I am picky about my friends. I tend to run with the church crowd. I am glad I am sheltered.
