not sick sounding at all, the feeling I get from a cockring is really hot and get really full balls. I guess if you wear it for several hours it could injure the system. I find my orgasm is really intense, and I drip a lot of precum as well. I know guys that wear it all day but find they don't get hard without the ring now. So need to use discretion. I am told that you can tell but skin temp. it should not get cool, if it get cold to the touch you are cutting off circulation.
I find if i wear it too long it is hard to get the ring off, as I wear a metal ring, but find if i lube it up I can slip it off after I cum.
