Well, I'm a 5"er on my BEST days and I'm certainly not proud of the fact that I'm not larger. I make good with what I have, but any man that is or considers himself a "A type" personality, I'm pretty sure wouldn't be proud of having a very small penis. Some men realize their success in life isn't dependent on their having a large penis or a large number of women to "bang" ... if he's financially & career successful and confident in his life, a small penis works just fine for him. These men don't set their life standards based on their penis size.
A type-B, submissive, bi-sexual male, however, might view having a small penis as a convenience that helps him fit in to the lifestyle that he desires.
Hopefully, you (if you're female) don't assess your husband's manliness based upon his penis size. If you do, then you need to look at your value system.
