Sayyiduna Muawiyah bin Haydah (may Allah be pleased with him) says: I asked, "O Messenger of Allah! From whom among our private parts (i.e., the areas that must be covered) can we see, and from whom can we not see?" The Prophet (peace and blessings be upon him) said: "Protect your private parts from everyone except your wife and your slave woman." Muawiyah says: I asked, "O Messenger of Allah! What if people are together with each other?" He said: "If you are able that no one sees (your private parts), then let no one see them." Muawiyah says: I asked, "What if a man is alone?" He replied: "Allah has more right that one should feel shy before Him." According to one narration (to clarify the matter), the Noble Prophet (peace and blessings be upon him) raised his hand and placed it on his private part.

Brief Explanation
Benefits: … From the following narration, one can gauge the manner of maintaining one's covering:
It is narrated from Sayyiduna Ya'la radi Allahu anhu, he says: "The Messenger of Allah sallallahu alayhi wa sallam saw a man performing ritual bath (ghusl) in an open place, so he sallallahu alayhi wa sallam ascended the pulpit, praised Allah and extolled Him, and said: 'Indeed, Allah, Mighty and Majestic, is Forbearing, Modest, and Concealing. He loves modesty and concealment, so when any one of you performs ritual bath (ghusl), let him conceal himself.'" (Abu Dawud: 4012, Nasa'i: 406)
Whether anyone is present or not, one should perform ritual bath (ghusl) behind a screen or by covering the places that require covering.
