i beg to differ, it looks like the diagrams i have seen for the phallodeum, guys. the shape of that tail end says its a male (females have more triangular 'tail' ends) its now been days in that state, is it still that way nate? in my research mice i have dealt with prolapse pe nis before (admittedly mammals have bones in there along with swollen tissue) and the mice went back to normal function once the tissue was recovered from the irritation. problem is while its on the outside exposed it may get damaged and aggravated. is the tissue still healthy looking like in the picture or has it become more red and swollen? is he eating normally?
