Mark Shanahan is a writer and reporter for the Boston Globe. He’s also a prostate cancer survivor who developed the podcast Mr. 80 percent for the globe detailing his experience with prostate cancer.  After his diagnosis and during treatment, Mark had to re-examine and rebuild relationships and consider what it means to be a man if your sexual function is at risk. Be forewarned, this episode has very frank discussions about sex and anatomy, so if you haven’t had the birds and bees chat with your kids, make sure they’re out of earshot.
