I guess Friends with benefits does not exist in the stages, as intimate friend do not involve sex or friends with benefits goes in another kind of friendship, LOL!!! Stages of sex friendship? HAHA!!!

What about friends with benefits what do you think where it can be included in these stages? Or friends with benefits is jsut a term made up by society? Or lets say good friends who have sex but they are not dating or hang outor seeing each other often just from time to time?
