Never had any negative comments. I would start with rubber, then go to metal. Look at JT's Stockroom for rings and how to size. Have fun & let us know how it turns out.
Cock Ring
I have several and use them all the time. Have metal and silicone. Also have a glans ring but it works better as a shaft ring at the base of shaft. Wife likes the way they look even when soft, have had the same comment from other ladies we have been with. The ring does not make for longer cock but it definitely makes for a much harder erection. As was stated before it also increases girth when hard. I feel it makes me last longer as well. It definitely keeps it harder after orgasm for additional pumping. Just my thoughts, luv em.
We've been playing with one for years and my wife loves it. Makes your dick super hard and engorged (think GIRTH) and I feel like it adds greater sensation to me. Have fun and give it a try.
My lady friend loves when I wear one. Increases my erection and hits her special spot as well.
I have a few .. love the new super stretchy ones they make now!
My lady friend loves it when i wear mine!!
Personal preference. I like mine tight and pushed as far down as it can go.

I use one but now I'm thinking how tight should they be?
The Pearl beaded cock ring is my favorite!
