The back wall of the vagina or the opening of the uterus. During childbirth, the cervix must dilate in order for the baby to exit the uterus. Women who don’t want a baby to come busting through their cervix like the fucking Kool-Aid Man (Oh yeah!) can wear a rubber diaphragm over their cervix during sex to keep the sperm out of their fallopian tubes. No jizz gets in, no baby comes out. Everybody wins.
1. Hand me that speculum, Honey. I wanna draw a bull’s-eye on your cervix.
2. Dianne’s vagina isn’t very deep. I feel like I’m playing racquetball against her cervix with my cock.
