For quite some time now, any photos at work, I do not touch anyone. I fold my arms, put them behind me or to my side. I don't put my hands on shoulders, legs or anything, even when casually talking. I know some people are "hands-y" because they will touch the person they are talking with, without it being sexual, but I do not ever do that. And I'm not offended if someone does. I had my boss (female) kind of put her hand on my shoulder briefly when she was making a point, but I knew that was just what she does and it didn't mean anything.
