Yes, folks, the cock is a wondrous thing. Try as we might when we're young and ashamed of them, we can't stop the wood from happening. It's all a part of growing up and accepting the hand we've been dealt - though it would be ever so much easier if we were not made to feel embarrassed in the first place. If we could casually hang out together with no worries we might sprout a stiffy.
Be thankful for each and every boner you get. Be proud of what named you Male...
Wood happens and it's a glorious thing!
As one Faithful Reader pointed out in a comment a while back: We should be able to take as much pride in what creates the bulge in our pants as women are allowed to be with their tits.
And there should be positively no shame in another man seeing it, soft, semi-hard, or boned.
