It is narrated about Sayyida Aisha Siddiqa (may Allah be pleased with her) that she was asked about a person who has intercourse with his wife, but his semen does not ejaculate. So Sayyida Aisha (may Allah be pleased with her) replied: I and the Prophet Muhammad (peace and blessings be upon him) also used to do this, and in such a case, both of us would perform ghusl (ritual bath).
