Aslan...of course, you're always entitled to your opinion, but I think the OP was asking more about whether a FWB relationship can work or if it's always a bad idea for the two people involved. Calling it immoral is more of a judgement on the whole concept, even if it does work for both parties and neither one is hurt by it. It seems to me that you may believe that sex outside of a committed relationship is wrong and there are plenty of people out there who believe as you do. However, this post really wasn't about that...it was simply asking whether two people who trust each other can share physical/sexual intimacy and continue to maintain their friendship.

I think that we all need to remember that not everyone has the same goals for their life (or even the same goals for particular periods in their life). Not everyone wants to get married and have children. So, sometimes sex comes in the form of a relationship that is not committed. I think this is perfectly fine for some people. But, if one does this in a serial fashion, it may just mean that the ability to bond if a longer term relationship is ever desired may be lost.
