Shit I dont know, I alternate between an old beat up jeep wrangler, a new(ish) Escalade or my Harley.
Slightly bigger than average cock. If 4 inches is average. And its not cold. And you dont measure too carefully.
Funny post. I really miss my Harley. Rode my brother's BMW when I went home last week. Handles great, but it's just not the same.
