Why most people these days only talk about sex when talking about a relationship?

Everyday I realize more that sex in a relationship is a fraction of what a relationship is, I’m a virgin (religious beliefs) and I had great relationships without having sex.

it made me value her beauty, voice, personality, charisma etc

I long for such commitment at this moment.

why is sex becoming a main thing when it comes to affection?
