Yeeesssss! I love kissing my husband! According to this article, scientists explain that a certain virus, Cytomegalovirus, can be quite dangerous to pregnant woman. When a couple smooches, the virus is passed from man to woman and over time she builds up an immunity so by the time she’s pregnant, the virus is no longer dangerous to her or her unborn baby. Interesting!
Disclaimer: must kiss for at least six months to build immunity.
