I've always wanted to know

[Person66]

I've always wanted to know, from a teen perspective (which I am no longer, but it was'nt long ago that I was) is it unusual to be tickled by another guy. cause as a teen my stepbrother's best friend and I were close. We'd play sports, video games etc. and sometimes he'd tickle me senseless, it was like torture for me (I hated it). too bad I was'nt into guys yet cause he was a hunk.
What I wanted to know is: What did this mean?
Was he trying to be: a brother, a friend, was he hinting that he "liked" me, or was he just trying to bother me?
