Why do guys measure their cocks?

Women measure their bust so they can know what bra size to buy ... but what is it with men and their fascination with cock size?

Mind you, I can't say I've surveyed all my male friends if they have or haven't and by golly, you won't see me asking a complete stranger this question ... but the guys I have asked at one time or other in my past have all admitted to doing this.

Oh ... correction ... all but one, who actually made a very interesting remark recently when I brought up this subject.

"Perhaps men measure themselves because they feel insecure and need some sort of validation. I never have. I'm made the way I'm made. "

Hmm ... interesting viewpoint considering he is ... ahem ... endowed.

Which makes me wonder ... how long are my nipples?
