In the U.S. (men) for the most part have never desired to remain virgins until marriage! In fact many males during high school would rather lie and say they had sex than to admit to being a virgin!
As for women the mindset started to change with the hippie "free love" and sexual revolution in the 1960s. Better birth control methods made it possible for women to have sex without having as much risk of becoming pregnant. In addition better career opportunities with higher salaries gave women more independence and financial freedom. This has led to many of them delaying getting married. The older one becomes the less likely they will remain a virgin.
Not many men are expecting women over the age of 24 to be virgins prior to marriage. In fact unlike most things that increase in value over time, being a virgin actually (decreases) in value the older a person becomes. No one sees a 45 or 50 year old virgin in the same light they see a 19 or 21 year old virgin. After a certain point people start to think there is something wrong.
Nevertheless life is a personal journey and each of us gets to march to our own drum. The most important thing about mate seeking is finding someone who shares your same values. There are over 7 billion people on the planet! Odds are there are more than a few people that would agree with any of us! :-)
Problems arise when people try to tell other people how to live their lives or insist they (change) rather than them seeking someone who (already is) in agreement with them.
