Perhaps the commonest preventive excepting the use of the condom is "coitus interrupts," or withdrawal of the penis from the vagina shortly before the action of the semen. No one can doubt that this is a perfectly safe method; and it is not considered so dangerous to the man as some authorities have formerly viewed it, but it requires a man of the strongest willpower to be certain that he has withdrawn before any of the semen has been deposited in the vagina. It is very difficult to determine exactly whether this has been done. The greatest objection to this is the evil effect upon the woman's nervous condition. If she has not completed her desire, she is under a highly nervous tension, her whole being is perhaps on the verge of satisfaction. She is then left in this dissatisfied state. This does her injury. A mutual and satisfied sexual act is of great benefit to the average woman, the magnetism of it is health giving. When it is not desired on the part of the woman and she has no response, _it should not take place_. This is an act of prostitution and is degrading to the woman's finer sensibility, all the marriage certificates on earth to the contrary notwithstanding. Withdrawal on the part of the man should be substituted by some other means that does not injure the woman. DOUCHES AND THEIR IMPORTANCE. The most important part which every woman should learn in the methods of preventing conception, is to cleanse herself thoroughly by means of the vaginal douche. After the sexual act go as quickly as possible to the bath room and prepare a douche. Lie down upon the back in the bath tub. Hang the filled douche bag high over the tub, and let the water flow freely into the vagina, to wash out the male sperm which was deposited during the act. Do not be afraid to assist the cleansing by introducing the first finger with the tube and washing out the semen from the folds of the membrane. One can soon learn to tell by the feeling when it is sufficiently clean. It is said, that the French women are the most thorough douchers in the world, which helps greatly in keeping the organs in a clean and healthy condition, as well as preventing the male sperm from reaching the womb to mate with the ovum. Following are some of the solutions to be used for the douche, which, when carefully used will kill the male sperm or prevent its entering the womb: Lysol--is a brown oily liquid which added to water forms a clear soapy solution. One teaspoonful of Lysol to 2 quarts of water (warm) makes a good solution for douching. Mix into a pitcher or vessel before placing it in the bag. Bi-chloride--Get the tablets blue or white from the druggist; the blue are less dangerous to have about because of the color. Always mix this solution thoroughly in a glass or pitcher before turning it into the bag. Never drop the tablet directly into the bag. One tablet to two quarts of water makes a splendid solution for preventive purposes.
