Kissing is an intimate act, not a sexual act, and you can’t get pregnant. Sexual intercourse is the act of penetration of the male penis into the female vagina, arousal and ejaculation. Pregnancy requires the interaction of a number of factors. First of all, there needs to be sexual intercourse and it just so happens that the woman is ovulating for the sperm to have a chance to meet the egg. The ability of the sperm to meet the egg also requires that the transport tubes are clear. If the fallopian tubes are adherent or blocked, the sperm will not be able to meet the egg and pregnancy will not be possible. The environment of the lining of the uterus also plays a crucial role in pregnancy. If the lining of the uterus is thin, uterine adhesions will affect the implantation of a fertilized egg. It is advisable for both men and women to use contraception, such as condoms, to avoid unwanted pregnancies if they are not sexually active and have no desire to have children.
