They're such a common occurrence that I sometimes think we get so used to the non-sexual ones that we take them all for granted.
Then there are the folks who continue to use outdated information to pass along on their blogs to unsuspecting readers. Or, they are trying to resurrect the old, totally incorrect "facts." Why would people do this? To strengthen shame and embarrassment among younger guys who haven't learned the facts behind the many erections we get in each 24-hour period?
For some reason, I've been waking from dreams - very vivid ones - which have absolutely nothing to do with sex. And, yet, my cock is hard. That is either one of many "Nocturnal Erections" we develop during sleep,
or "Morning Wood" which we guys experience when we wake.
These boners have nothing whatsoever to do with sexual arousal. It's the body supplying blood oxygen to an area which doesn't receive enough without an erection developing.
They happen during the day, too - without warning.
A man can be in the middle of a business meeting and his cock will begin to expand; nothing sexual about it.
As happened to me over the weekend, just walking through the grocery store, my cock snaked its way down my pant leg.
Blood Oxygen Erections (BOE) happen. They have nothing to do with being horny, thinking about sex, or needing to get our rocks off.
