Does being a dominant have a certain set of physical standards to measure up to, for example?

On tumblr, someone posted this:

I wish my ex-husband Scott could have been this guy for me… but the reality is, you can’t be a Dom with a four inch penis. Just. Not. Possible.

My reply:

I respect this woman’s right to state her opinion. As a cuckoldress, it seems like a pretty standard opinion.

However, I beg to differ.

The size of your cock (the size of your wallet, your boob size, how skinny you are, a leather allergy, color of your skin) does NOT have any factor in how dominant of a person you are (or are not).

Period.

I know men who are short, fat, ugly and hung like hamsters who still do just fine with their dominance.

In fact, I know more than one submissive woman who PREFERS a smaller cock. One woman I know HATES anything over 5 inches. It’s uncomfortable for her.

So, again, I respect the fact that you cannot be THAT WOMAN’S DOMINANT with a four inch penis. That’s fair, for those who prefer larger cocks and associate those to manhood/aggression/dominance.

However, it has no bearing whatsoever on whether you can be “a dominant” in my view.

Your thoughts?
