Can the "looks" tell you how you might want to PE

So I’ve been thinking about something that may or may not make sense. Is it possible to tell what will work better by examining your penis? My penis has multiple large veins, a more “vascular” (I would say quite a bit more vascular than average) penis I guess is how you’d put it. So I was wondering, do certain workouts work better or worse when applying them to more or less vascular looking penises? For example, will you see greater results when jelqing a more vascular penis? Or maybe less? Or would a less vascular penis have more room to “improve?”

Unless you can see the structure of your tunica (you can’t) I don’t think ‘looks’ are going to help you. Vascularity or lack thereof won’t help with gains, except that as veins get larger they add a little to your girth.
