Bob, how do you wear your bag horizontally or vertically? I wear mine horizontally and when people hug me, I often keep one arm down near my side to prevent them from hitting the area.. so it is protected.. I don't know how that will work on the motorcycle though.. "what's the squishy thing I feel". But my point is protecting it the way I do gives me an edge.
Also, have you ever come across a person, usually a guy friend, who doesn't know about your bag and you're talking face to face with him.. then he goes with a finger and hits your belly like to get your attention? I mean it's a touch touch moment.. people do this all the time. What I don't like is if people know about the bag.. and still touch me in that area..
As a person with a hearing aid in my right ear, I often get people talking directly into my left. That's what I am talking about. Or they try to whisper in my left ear. That sucker (the ear) is dead. So what do I do, I lean in. (Picture that for a moment)
It's just stupid shit. Hugs are good. Just know how to protect the area. Nothing wrong with keeping an arm down or along your stoma side. Just hate it when people have to tap/touch that area to get my attention.
Also, re: hug types, if you wanna analyze this. The pull-in hug and bend-in hug. Vertically speaking, I have no trouble with either. And you say.....
