Personally, I believe that one should wait until a little later in life. I think that it does change ones view of intimacy. and can create a wall that keeps one from pursuing traditional relationships and the emotional rewards they can bring.
I read the posts on how it is "cheaper' to see professionals than traditional relationships. To me, this is very short-sighted and reduces the value of romance to only the physical benefits. For me, the value of true romance completely goes beyond the borders of a physical relationship.
and I do know that, for me, the frequent use of professional companionship including longer term arrangements has reduced my pursuit of more traditional romance and the depth that they can bring.
