Erect penises have appeared in erotic (sexually exciting) art for a very long time. Pictures of men with erections appear on ancient objects and in paintings. In the past, the erect penis was also a symbol or sign of health and fertility (the ability to give life). Ancient Egyptians, Greeks and Romans believed in gods that had erect penises. Today, erect penises do not often appear in artworks or movies because many people think that showing a man's penis when it is erect is obscene (not decent). Men with larger penises are often thought to be more handsome, manly and powerful. A lot of people also believe that men with bigger penises are better at making their partners feel good when they are having sex. However, this is not always true.
