I think that if the sex is good in the beginning, that the romance and variety would have to be maintained to keep the desire high. I highly doubt that anyone on this site can honestly say that their W became LD without some help from us. But knowing what we know now, don't you think that we we would be much more vigilant in our own behavior and in our communication with future partners? I think communicating a vision of a life together will give you some clues. Throw some sexpectations and judge the reaction.
In essence, it's a gamble. IMHO.
