I've noticed this trend in film and tv series too. Relationship plots used to see a semblance of courtship and dating activities, but now that chemistry building is replaced by sex being the main activity before even knowing if there's a desire to truly be with the person. Apart from agendas, I think it's a writing cop out in order to heighten the audience's emotions and open the door for drama and messy webs to tangle characters in.
