What is the difference between friends with benefits and dating? If you are friends, you probably go out (as friends) and do fun things together just like couples, so if you add sex/kissing to that, aren't you basically dating?
Well both are social constructs though friends with benefits by it's design is socially more flexible then Dating.
Dating implies exclusivity in the emotional and sexual relationship over the defined Dating period.
Friends with Benefits implies a traditional friendship that includes a sexual component but because it is a newer concept that falls outside conservative norms it has more room to define the degree of friendship and the degree of exclusivity in the emotional and sexual components.
a friends with benefits is someone you have just for sex. you don't want a real relationship with that person. if you date someone then you actually want something serious. maybe you get quickly sexual, but you don't wanna limit it to that.
