Measure them by how well they perform orally and in bed.

me try to not measure'em at all ....

That makes no sense. Everybody measures everything in life. Measurements are the way we decide about things in your life:

What food do you like? The food which tastes better. You measure pleasure.

What games do you play? The games which are most fun. You measure their fun.

Why not touch the hot stove but the hot babe? Because the stove burns the babe doesn't.

You measure pain. And pleasure. You measure what contributes positively or negatively to your life. You use these measurements to decide what to keep and what to get rid of.

A hot girl is more valuable to a man than an ugly girl. That's why hot girls get free stuff and ugly girls don't. People invest in things they deem valuable for them, that have worth for them.

These ideas of "don't measure" or "everyone's of equal worth" are purely romantic notions, they are sentences that feel good, but they don't make any sense whatsoever.
