I certainly think it's possible, but it's never a permanent state. It's an intermediate stage between one night stands and a full blown relationship. I certainly see the benefit to such an arrangement, especially in this day and age of STDs...no dinner, no dancing, no emotional attachment, just sex for recreation. Kind of like having a workout partner for the gym. You socialize with them while working out, but you don't go out to eat, visit with their families or go to cookouts or barbeques with them...you go, workout, maybe socialize a bit while you're jogging, and when it's done, you go your seperate ways.The benefit of being FWBs is that you don't throw your health on the craps table for STDs like you do with one night stands and you don't have the pressures of a full blown relationship. At this stage in my life, that's about what would appeal to me because it's right for me...for now. It will likely change later, when I become more emotionally stable and secure and will want that something more out of a relationship.I think the important part of a FWB relationship working is that both people need to be on board with the same attitude. As long as you're both able to maintain the emotional distance necessary for such a relationship to work, then I say more power to you. But the second one of you starts developing feelings for the other or wants more from the relationship, then one of two things is going to go...either the friendship or the benefits. Like I said before...it's never a permanent situation, but even the benefits of that relationship ending are fairly good...either you grow closer together and you end up having a relationship that's successful or your friendship ends, which means less pain as there wasn't too much emotional investment in the first place or the benefits end, in which case both people maintain their friendship but are both okay with seeking other people to fulfill their needs, and nobody is hurt emotionally.
