Since you’re required by law to tell anyone you have sex with that you’re HIV positive or you can be charged with manslaughter (involuntary I think), I’d say he’s just making sure he’s covered if he has drunk sex that he doesn’t remember.
Still in poor taste, though.
Aside from the obvious nastiness of the HIV situation this is an ugly ass tattoo, why would you want something that big and UGLY, is it seriously something someone got before going to prison, WTF was this captain Moron thinking.
Medical evaluations (including blood work) are required of all prisoners upon incarceration. HIV positive inmates are held in separate areas than inmates that don’t have it. This serves absolutely no purpose other than giving his new boyfriend something to chuckle about.
