If you were wearing underwear from the beginning to the end, and your and your boyfriend&39;s genitals had no contact during the whole process, you should not get pregnant.
However, if the man&39;s genitals have entered the woman&39;s vagina and no proper contraceptive measures are used, even if the man did not ejaculate, or only ejaculated outside the woman&39;s body, the woman still has a chance to get pregnant, because the man&39;s bulbourethral glands will secrete a small amount of fluid when he is sexually excited, which has the effect of neutralizing the acidity of the urethra so that sperm can pass through the urethra smoothly during ejaculation.
Although this secretion is different from semen, it also contains a small amount of sperm, which is enough to make a woman pregnant. In any case, if you choose to have sex in the future, you need to think clearly in advance and take adequate precautions to prevent accidental pregnancy and sexually transmitted diseases.
