It can delay ejaculation and for the gentlemen who have a hard time getting hard, or getting and staying hard, this is a great tool for them to get the desired effects. Just make sure you get one that's not too small, lol, or too big.

A recent conversation with a provider during the rest phase included a discussion of sex paraphanalia.  She indicated that a cock ring can delay ejaculation, along with other benefits.  Any comments and/or advice on their use?
Memory tells me the old web site had a search function, but I couldn't find one now.  I suspect this topic has been discussed before, so a way to find a prior thread on this subject would be appreciated.

Cock rings are a great addition to the bedroom.  It makes you rock hard and shoot harder as well.  My advice for any man thinking of trying one out would be to try it solo first.  You can get a feel how your body reacts to having one on.

They add pleasure for both parties.

I just discovered Cock Rings.  I bought a pack of clear latex that contained three sizes along with a bottle of "Gun Oil" a water based lubricant.  When I'm horny and alone out they come. The rings make your dick more sensitive, all the little veins come out and the orgasm is great.

I've been using a sort of elastic band for years.  Never got a real cock ring.  From personal experience, i dont think it delays orgasm.  In fact as another pointed out, it intensifies feelings, so it may make you shoot faster.  I've used the bands for so long I can't tell anymore.  

The main reason i use the bands is because I hate when one of my balls draws up into my body or gets pushed up there by too much pressure (thigh or tongue being the usual culprits) .  Bothers the heck out me cause it just feels so strange.  I know it sounds weird, but i've had friends say the ball thing has happened to them and they didn't like it either.  Sorry if TMI, but just wanted to point out potential other benefit.
