    While it's true that erections can develop in response to a wide range of physical, mental, or emotional stimulation -- young boys and men may get erections for no clear reason -- it's a bit more complicated than "see boobs (or butt, or wildebeest, etc.), get hard." In fact, the journey that ends in an erection is a multi-step process that involves a number of different body parts and systems, including the hormonal, circulatory, and nervous systems.
