Does the argument of husband dick vs vacation dick prove that size matters from a purely pleasure point of view?

I’ve been confused about these terms for a while, but the terms boyfriend dick, husband dick, and vacation dick are often put against each other (or, at least the last two are). First and foremost, I’m curious as to how someone would define these terms and what the difference would be between the first two. But also, and mainly, wouldn’t this prove that size matters from a pleasure pov? Just that “husband dick” seems to be the dick that’s relatively average-sized and can be taken repeatedly (from a husband), whereas vacation dick is a bigger dick that’s taken rarely (like on vacation)? Am I wrong? Thoughts?
