The male penis is not inserted into the vagina nor does he ejaculate, but only rubs against the vaginal opening is also a possibility of pregnancy and therefore of ectopic pregnancy. When the male penis is erect, the urethral opening secretes a clear, sticky prostatic fluid that acts as a lubricant, and this fluid contains a small amount of sperm. If the woman happens to be ovulating, the sperm at the vaginal opening will swim into the fallopian tube and unite with the egg to form a fertilized egg, which will then return to the uterus to be laid to complete conception. If, on the other hand, the fertilized egg does not reach the uterine cavity and then lays, an ectopic pregnancy occurs. Therefore, it is possible to become pregnant simply by rubbing outside the vagina, and it is important to use effective contraception throughout if you have no plans to become pregnant. If there is no pregnancy, there will be no ectopic pregnancy.
