Through the FRP, inmates can be visited by a legal spouse, child or children, or other immediate family member or partner. "Technically, I'm not sure if you can have a girlfriend [visit]," Ryan said, "but people did. They’d lie and say it was their sister, their cousin…"
During a conjugal visit, people are permitted to engage in sexual activity -- but mostly, it's actually meant for family time: chatting in a non-prison setting, offering some semblance of a normal life in order to keep the integrity of a family unit together. These visits are intended to incentivize prisoners to comply with prison rules, be on best behavior, and have a higher chance of success upon re-entry to civilization.
In short, it's not just a shaggin' wagon. "A lot of moms would come," Ryan said, "a lot of parents, a lot of kids." In Connecticut, there actually has to be more than one visitor -- a spouse or partner is required to visit with the inmate's kid in tow. In Washington, if two inmates are related they can schedule a mutual visit with civilian family members. And actually, only 48% of conjugal visits in New York in 2014 were with spouses.
