Unsurprisingly, when some rational thought is put forward to these things, the body regularly undergoes performance checks so things are still working.

The mechanisms related to reproduction are in general the single most important outside of the various systems in place keeping something alive... so that it can eventually reproduce.

So the fact that a male body will spontaneously get an erection at times, more so at a time the rest of the body is inactive therefore making it a prime time to check things, should be of no surprise to anyone with half a brain.

That is of course still half a brain more than these chucklefucks pushing these retarded opinion pieces have.
