Question

what does having erections mean what causes them to take place?

Answer 1

An erection is when lots of additional blood flows into the area getting erect. Usually, when it is the penis or clitoris getting erect, it means the man or woman are interested in sex.

Essentially, there are lots of "empty" collapsible areas in the penis that fill with blood, causing it to expand and stiffen. It's partially kind of like a ballon, in a way.

Sometimes, if a guy has to pee, he gets an erection. An usually, there is a morning wake-up erection. And sometimes, when you're sleepy and stretching/yawning, you can get a temporary erection...
