This narration is reported about Sayyidah Aisha (may Allah be pleased with her). She was asked about a person who engages in intercourse, but his semen does not ejaculate. Sayyidah Aisha (may Allah be pleased with her) replied that she and the Prophet Muhammad (peace and blessings be upon him) also used to do so, and in that case, both of them would perform ghusl (ritual bath).
