I will be honest as you asked to. I think it's not exactly a reason to be on LPSG, your johnson is not the thickest in the world, but it has a decent length and seems to stand up strongly. I'd say he is on the larger side of average and definitely nothing to be ashamed of.
You don't want to have a dick that needs to be on a large penis support group because when you actually have to, it is a problem, not a blessing. Hence the support group.
