eli5 How do men get a boner and how does the brain know when men are aroused?
In: 2
Men get an erection when blood is directed to the penis. The cause of this is not always sexual arousal. Sometimes they are very random. Much like a heartbeat, erections cannot be controlled consciously, even though certain practices (deep breathing, relaxation, flexing surrounding muscles) can be used to end unwanted erections.
