Beyond puberty most of us don't continue to wake up with concrete slabs the size of tree trunks in our pants causing the morning urination ritual to require a skilled horizontal lean over the toilet in order to hit the target, and that's why Horny Goat Weed was created! We as men don't understand damned thing as we develop our male sexual drive, and come up with ridiculous terms like the morning wood elf to joke about with our teenage friends who know even less damn things than we do. Then we grow up to actual need this morning wood elf to perform meaningful sexual functions with another actual human being instead of just a hand. But as we age hormones aren't raging like the niagra falls anymore and life can require much more from our morning wood elf than as young kids.
