Is it possible for a visitor to have a sexual encounter with an inmate as an arranged visitation event?

That might also be referred to as a "conjugal visit" where a spouse can have a sexual encounter with their related inmate but this is only available in four state prison systems, California, Connecticut, New York, and Washington. I will say that I saw a lot of sexual activity in the visiting room where the guards are lax, not paying attention, or are paid to look the other way.
