Friends With Benefits?

It means that a guy doesnt want to have to deal with the emotional side of a relationship and just wants the physical benifits from it. It is not that he does not find you appealing (probably the opposite) but he thinks that you just want the without the emotion to. And you became the friend with benifits because you had with him and werent going out or otherwise engaged ina relationship with him and you let it continue to boot. If you want it to stop: don't have with him.
