The Messenger of Allah (May peace be upon him) made a concession in the early days of Islam on account of the paucity of clothes that one should not take a bath if one has sexual intercourse (and has no seminal emission). But later on her commanded to take a bath in such a case and prohibited its omission.  

أبو داود:٢١٤ – حَدَّثَنَا أَحْمَدُ بْنُ صَالِحٍ حَدَّثَنَا ابْنُ وَهْبٍ أَخْبَرَنِي عَمْرٌو يَعْنِي ابْنَ الْحَارِثِ عَنِ ابْنِ شِهَابٍ حَدَّثَنِي بَعْضُ مَنْ أَرْضَى أَنَّ سَهْلَ بْنَ سَعْدٍ السَّاعِدِيَّ أَخْبَرَهُ أَنَّ أُبَىَّ بْنَ كَعْبٍ

أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ إِنَّمَا جَعَلَ ذَلِكَ رُخْصَةً لِلنَّاسِ فِي أَوَّلِ الإِسْلاَمِ لِقِلَّةِ الثِّيَابِ ثُمَّ أَمَرَ بِالْغُسْلِ وَنَهَى عَنْ ذَلِكَ  

قَالَ أَبُو دَاوُدَ يَعْنِي الْمَاءَ مِنَ الْمَاءِ
