There isn't a 'set age' when a boy gets an erection; it can happen at ANY age in a male's life, and yes, that includes babyhood. When young boys have them, they're not necessarily caused by being sexually excited, but they CAN occur. Most boys start getting erections because they are sexually aroused around the age of 12 or 13, although it can be earlier or later.

NEVER make fun of a boy for getting an erection! If you notice, pretend you didn't. The boy is probably really embarrassed as it is. Every guy gets an erection sometime.

Even baby boys get erections. It is an involuntary, normal part of development and happens all through life. Boys start noticing their genitals and the feelings that can be obtained from them in toddlerhood.

Depending on the sexual maturity of the boy, self-stimulation to cause deliberate erections can start anytime in childhood.

It is at adolesence, generally from the age of 10, that erections become regular occurances and masturbation becomes normal. Ejaculation is generally not possible until the boy is a little bit further into adolesence.

that all depends on how long it's being stimulated. You could clearly stay hard for hours if it is being aroused and not let it ejaculate.

An erection can happen even before birth. It is just caused by blood flow to the penis.

All males have erections, even before birth. It is partly necessary for blood to flow to the penis to nurture it.
