We all need that kind of prayer friend. I fell for that myself a couple of times after my chrismation. The point is that for the non-Orthodox, and even to many Orthodox, intimate contact is seen as just one more form of tenderness reserved for "that special person". To confront that is to break the relationship. To succumb to it - and as you said, not without enjoying it - is not pleasing to God.
But I am to find the girl who can even conceive of a pre-marital relationship that will not include that and fight the good fight with me in that regard - because I know that the temptation is in me first.
God have mercy of us all! See the culture we are, the weakness of our hearts, and guide us, teach us, and strengthen us!
