What exactly does a cock ring do?

I have one in my sex toy box but I have never used one. I don't really know what they are for. I know it vibrates and that's supposed to feel good for me. Does it make the man stay hard longer? Because then I wouldn't want to ask my boyfriend to wear one because he might be embarrassed. I just really want to know what they do.
