If one thing has changed dramatically over the years, it's the freedom people now have in pursuing sexual relationships. When I was young, suffocating restrictions made it very hard to follow your natural desires.
It all sounds absurdly draconian now, but in those days parents monitored their children's behaviour very closely. You couldn't simply fancy someone and let things take their course. That was unheard of.
Parents would have very strong opinions on the person you fancied and would strenuously resist any "unsuitable" match. Sexual activity, or even what was called "heavy petting", was strictly prohibited until you were married.
You were expected to "go steady" for a suitable period, then get engaged for another year or so, after which you would get married (that is, if your parents still approved of the spouse-to-be).
The fiancé would of course have to ask the fianceé's father for her hand in marriage, while the alternative of cohabitation was still unthinkable.
Once married, sexual activity was strictly confined to the missionary position, and any kind of "kinky" or non-vaginal sex was considered abnormal. The only natural relationship was the heterosexual one, homosexuality being firmly in the closet and preferably never spoken of.
Nowadays, after the steady erosion of one quaint restriction after another, the situation has changed out of all recognition, with the young having almost complete freedom to form whatever relationships they like and let them follow their natural path.
Parents have been relegated to their proper position, interested bystanders who will only give advice if it's asked for and will always try to support their children's choice of partners.
Youngsters today are incredibly lucky to have such freedom, and not knowing what previous generations had to contend with, they mostly take it for granted. Which is not surprising.
Of course some of them take these new freedoms too far and make a mess of their lives. But better that than being bound hand and foot.
