Woo-hoo! Check me out, healthily progressing and stuff
I've heard that evolutionary theory before and while it seems to
almost make sense, to me common sense goes against it -- like the fact that the whole "cougar" phenomenon (which is not new by any means) is a thing, which seems to defy the idea that youth=fertility/longevity=sexual attraction. If all or most straight males would prefer the company of younger females by nature, younger men being sexually attracted to older women would be much more rare, or so it seems to me.
It doesn't seem to make evolutionary sense, either, that someone whose brain is not yet fully formed would naturally be the best choice to nurture and protect one's offspring. Teenagers are notoriously self-centered, impatient, and require more sleep than any other segment of the population save newborns. While I was a teen mom and a damn good one, I don't pretend that it's the ideal situation.
That said, sex is nice; I don't necessarily believe that all human sexual urges do or have to make evolutionary sense. Sometimes we just want to get it on, amiright?
I think it's much more likely that this "it's natural, evolutionary" idea is something that some few with less than honorable intentions (
not you, Nova!) have latched onto and repeat enough times, hoping it will stick and excuse their own twisted desires -- much like the "it's messed up that you can sleep with a sixteen year old but can't look at/take/share explicit photos of them" thing. Fallacies? IDK; I feel like that word should be in this paragraph somewhere.
As always, JMO, and I ain't nobody!
