obstetrician

— The preference for tightness during intercourse is so well known in Western culture that U.S. obstetricians even have a term for the extra stitch they often perform when doing episiotomy repairs following childbirth: the "husband's stitch." The husband's stitch is intended to produce a smaller vaginal opening, to counteract the natural stretching of the tissues from sexual activity and childbirth and even to make the opening more constricted than it might have been before.
