As long as you always wear a condom during sex, you will not get pregnant even if you ejaculate. Condoms prevent the sperm from entering the woman’s vagina, thus preventing the sperm from meeting the egg, so that you cannot get pregnant. However, when wearing a condom, you must remember to use it all the time, because some young people do not wear a condom before intercourse, and then put it on when they are about to ejaculate, before ejaculation the man already has a small amount of prostate fluid into the woman’s vagina, and there will be a small amount of sperm in it that can easily make the woman pregnant, so this situation is still not reliable. If you use a condom for contraception, it is best to use it from the beginning of intercourse.
