Um... fucking the forty-years-your-senior doctor who delivered you? I wouldn't even do that:

Mrs. Santorum, 51, apparently wasn’t always committed to the [pro-life] cause. In fact, her live-in partner through most of her 20s was Tom Allen, a Pittsburgh obstetrician and abortion provider 40 years older than she, who remains an outspoken crusader for reproductive rights and liberal ideals. Dr. Allen has known Mrs. Santorum, born Karen Garver, her entire life: he delivered her in 1960.

“Karen was a lovely girl, very intelligent and sweet,” says Allen, who at 92 uses a walker but retains a sly smile. A wine aficionado who frequented the Pittsburgh Symphony and was active in the local chapter of the ACLU, he lives with his wife of 16 years, Judi—they started dating in 1989, soon after he and Garver split—in the same large detached row house where he lived with the woman who would become Santorum’s wife. He and Garver also lived for several years in another house a few blocks away. “Karen had no problems with what I did for a living,” says Allen, who helped start one of the first hospital-sanctioned abortion clinics in Pennsylvania. “We never really discussed it.” (The Santorum campaign did not return repeated requests for comment on the relationship.)

The six-year-long May-December affair, which was always out in the open, began in 1982, when Garver was a 22-year-old nursing student at Duquesne University. Allen was then 63.
