Um, the topic title! FWBs can be fun, I've done it a couple of times. Dr. Rock is right on target about the personality types though. Some people are better with it than others. Also, you have to think about yourself, and if you can be happy with this kind of arrangement. I was lucky enough to meet some really great guys who, like me, where just in a transitional place where a relationship was not what they wanted, so it worked out well for a short time, and we still had mutual respect and enjoyed each others' comapny. It's just important that everyone know from the start that it is what it is, then enjoy!
