1. When a man's penis is enlarged due to natural attraction to another person. Men will normally get a hard one after looking at woman who are posing in a manor that is 'stiffening' to a man. See example. Erections are also obtained during sex when fooling around with the opposite gender. However some teenage boys are unable to control this urge and often get an erection in an embarassing situation. Some men get an erection over another man ; this is the sure sign of being gay.

2. A building that has been created - generally through man made resources.
Description 1 : The man got an erection after looking at a semi-naked woman who was sucking her finger seductively.
