Interesting question,we have been asked this by one or two people before,dont think we have every really given a straight answer.
So many people seem to want to keep their RHP friends and so called normal ones apart.
Our feeling is yes this is a sex based web site ,but we feel we can meet other like minded couples on here,and mabe form a friendship from there.
After all one only needs to venture into to town and on any given weekend can pick up a couple or single just for a quick wham bamm thank you man.
Therefore we as a normal couple LOL who are a little shy do appear to on the same wavelenghth as R8d_4U ,as im sure many couples if honest with themselves would be.
