Ghusl becomes obligatory when the private parts meet
Hadith 82
أَخْبَرَنَا وَهْبُ بْنُ جَرِيرٍ، نا شُعْبَةُ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، وَأَبِي رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: إِذَا قَعَدَ بَيْنَ شُعَبِهَا الْأرْبَعِ، ثُمَّ اجْتَهَدَ فَعَلَيْهِ الْغُسْلُ.
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "When he sits between her four limbs and then exerts himself (has intercourse), then ghusl (ritual bath) becomes obligatory upon him."
