This imo, but being 'friends' is one of the most misused words when it comes to boy/girl relationships. Judging from your story, you guys are more than friends for being that intimate.

You got to reseolve what your feelings ar for him and vice versa. Don't think that what you are doing is an act of friendship. If you don't see him as anything more as a friend, then stop being that intimate with him.

I'm a guy, and if one of my girl friends would be that intimate with me, then I would think that she wants to be more than friends. If not, then, I might think my friend is just using me or something.
