eli5 How do men get a boner and how does the brain know when men are aroused?
In: 2
Great news. It’s a multilayered thing.
Layer one: human beings (be they female, male, or other) have a pair of reciprocating/antagonistic executive modules in their brains. One constantly searches your environment for cues to get more aroused. The other constantly searches your environment for cues to get less aroused. These modules send commands to your body.
Layer two: zooming into the case at hand, if you develop an arousal and you wish it weren’t happening, it’s quite possible that the tension of that wish will feed back into your sexual acceleration system and make it all worse. So then you’re stuck with an undesirable hard-on.
