Without safety measures extracorporeal ejaculation can lead to pregnancy. This is because before ejaculation, a small amount of fluid may come out unconsciously due to sexual arousal, and this fluid usually contains sperms, which may also lead to pregnancy in women. In addition, during the process of ejaculation outside the body, if a little control is not good, it is likely to lead to semen into the vaginal body, which can cause pregnancy. Extracorporeal ejaculation is not a very reliable method of contraception, and if you are not planning to get pregnant for the time being, it is recommended that you take safety precautions when having sex.
