Well, for what little my opinion may be worth, I'll voice it anyway. Personally, I think there are ones that have a "smoother look" than others. But the reason I don't care is I don't ever want to begin analyzing what I might like or not like, because eventually a woman will notice how your facial expression changes when you see it.---you know, you get that "eewwwww" look on your face.?. Anyway, I don't ever wanna girl to look at my dick and give me the "eewwww" look. That would suck in the heat of the moment.

I guess I'm just not vain enough to form a strong opinion on the subject--like or dislike.
