Is holding hands with another guy cheating?

i was just wondering if holding hands with another guy while you have a boyfriend cheating? even if its someone you grew up with? I have know this guy since elementary school used to be attracted to him but now he's like a brother. well we were at camp this summer and we went walking with a group of friends and two of my friends who were kinda dating were holding hands so my "friend" his brother and another girl were just walking and I said guys don't leave us out so we all walked hand in hand it was sweet I know there is nothing sexual about holding hands but I don't know how my boyfriend would take it
