11- Isolation (meaning a man isolates his water from a woman’s genitals at the time of ejaculation or at the end of intercourse). One of the oldest and prized methods of contraception. It is a method that was followed in the era of the Prophet - PBUH - but it is not medically recommended:
A - Because it may harm women both physically and psychologically: Congestion of the genitals. It can lead to bleeding during or after menstruation, accompanied by excruciating pain. Then the uterus swells and the woman develops nervous disorders or nervous tension. She becomes crying for the most trivial reason, and her marital life ends.
B - It certainly harms the man psychologically, because at the time he loves so much. To stick to the woman completely is to stay away from her. He suffers from that psychologically the most pain. Rather, many men prefer - therefore - that one of them not have intercourse with his wife instead of having intercourse and isolates himself.
