What would a good option for someone who's never used a cock ring before? I'm thinking about getting one for my boyfriend.

the metal cock rings are made from stainless steel, or the cheap ones are chrome plated. I have never had one rust, but then I dont leave them laying around wet either. You should be fine if you take the time to care for them.

I didn't know that pyrex rings existed. I have the Omega and several other stainless steel rings and love them all. The Omega is my favorite because the round profile never pinches or digs in.
