Friends with Benefits

I disagree with friends with benefits.

 I think it has some things well, for example, you already know that person, your friends, so Is more easy to be related.
But you know that is a probability that you have strong feelings for your friend.
when you spent time, share the same things, maybe your feelings start to grow up, and you can control your feelings, It's something that we never going to control, because you didn't choose the person you're going to love.
so is better that your friends are only your friends, and look for a real relationship.
