Does it help or hinder contestants on reality shows to have romantic relationships with each other? Why?

Question

My question doesn't include the kind of reality show where the goal is to develop a romance.

Answer 1

it could go both ways for instance if you were on a show like real world vs. road rules challenge you pick the person you like to stay in the game with you, but if you were on a show like survivor an someone else also like the person you like they could go tell their friends to vote you off
