The 'Correct' Formula?..

According to a very conservative someone (who's still a firm believer of certain traditions, e.g. virginity + marriage), the proper sequence goes like this:-

First comes Love, next comes Relationship, Marriage comes right after and then finally, comes Sex.

• Love + Relationship = Marriage + Sex

But in the modern context today, the re-arranged sequence goes mostly like this:-

Sex 'Comes' first, next comes Relationship? (or sort of...) and if ever, comes Love?, then finally/hopefully Marriage? will come along.

• Sex + Relationship? = Love? + Marriage?
  

Maybe we are indeed messing it up..
Perhaps that's why everything ends with a huge ? ?
