The implications that those who are easily aroused engage in more high risk behaviors (sexual or otherwise) combined with some high risk activities getting high

The implications that those who are easily aroused engage in more high risk behaviors (sexual or otherwise) combined with some high risk activities getting higher risk in the age of AIDS and fentanyl leads one won wonder if the Darwinian forces will result in a selective breeding of men with erectile dysfunction as those who are more easily aroused remove themselves from the gene pool. This is probably not the case, given that it's not so hard to propagate their genetics before that point, but it's a non-zero risk, especially in the age of Plan B and abortions, when their partners are less likely to carry the resulting children to term. There is also the matter of onset; presumably while the age of onset of erectile dysfunction has been going lower in recent years, a 20 year old is still a 20 year old. But I will plead ignorance on this matter; when kids are accessing porn in their crib on the iPad that's babysitting them, assuming they don't have death grip syndrome by the age of 10 is a big assumption.
