I think it is probably a little dangerous, but not necessarily wrong, per se. I have had guy friends develop this emotional itimacy with me, and I had no idea they were doing so, I thought we were just really good friends, and then they tend to get physical which made me uncomfortable.
On the flip side, I became very emotionally intimate with my ex, and still am, we still talk ad do things together because we are good friends. He never had marriage in mind though, and was never physically attracted, so whereas he has the emotional intimacy as well, he only considers me a really good friend. I heard the term "flirtationship" recently and I think that's what it is- more than friendship, but not headed toward a relationship/marriage.
So, whereas they can be two sides of the same coin, I think they should be considered separatly as well. I have had physical intimacy with guys (not sex though!) and attraction between us, but no emotional intimacy- just as you can have emotional intimacy and no attraction...
I guess I am just (cough, choke) to old fashioned and practical for that "flirtationship" stuff. The way see it, you've got choice A or B.
A. He goes off an dates some girl and this friendship gets ditched at least temporarily therefore.... I get hurt.
B. I go off and date some guy and that guy does NOT like my having said "flirtationship"/friendship, and the friendship gets ditched, and.. I get hurt.
It's one thing to accidentally get hurt. But, it's totally another to go running towards the cliff, ya know? I was born at night......but not last night.
