It's a very touchy topic at best. Let me think, um....I agree with it on some grounds. If they were together then broke up and then started to be friends with benefits, I just think that's just stupid. I mean, if you just wanted to fool around from the beginning, go ahead.
But females tend to go the wrong path of the f-w-b agreement. They get attached, well, most of them. They believe it's somewhat of a real relationship and when the male decides to end it, the female counterpart gets upset and feels used.
With men, they don't get attached as fast but it sometimes accure. But to my experience, if they knew a friend who's a girl whom would like to fool around with them, they aren't going to stop them, lol. I mean, come on. Think about it.
I've been in one f-w-b situation. It was fun while it lasted. It was 3 months. Not a lot. But, we're still cool. We knew each other for two years before we started. But we were lovey dovey like. Hold hands and junk. It was wierd at first but it was hilarious towards the end. We were voted greatest hook up by our friends, lol.
Here's some advise. Make sure at the end you'll still be friends. Because if you don't, it's going to get real awkward, I promise you.
