So cock rings seem to be a knew (new) trend lately & I have never understood them but yet why would I when I don't have a WINKY.. So my question is...it can make a dramatic difference in girth especially if you are a grower ... as I am ... showers (not shower but show-ers) --- I am not sure how much difference it would make --- I assume it might be more like Viagra for them making a firmer erection. I do not believe I would use one in combination with Viagra or other ED meds as they have been know to cause long lasting erections and the point of the cock ring is after ejaculation the penis would soften and the ring would slip off naturally as the penis gets smaller and less blood is forced into the vessels. If that mechanism stayed open I am not sure the penis would deflate as normal and the likelihood of getting stuck would seem more prevalent.
How do you go about deciding which one is right for you?
the size you use / choose depends on how much your penis grows in circumference at erection. So, it should probably not be a decision you should get involved in other than your SO. I am sure an expert cock worshiper such as yourself is aware that different penises grow at different rates --- some are for showing and don't grow much larger at erection and some are for growing and can double or triple or more in size as the blood flows in --- the more you grow the looser you want the cock ring to fit. You want one tight enough to keep the blood supply in the penis without getting so tight that it allows no blood to escape which can make it difficult or painful to remove. when in doubt go larger and work to smaller. Place your tape measure at the base of the erect penis under the balls and measure tight enough that when the man does a few kegals you can see the penis being larger or firmer. Divide that measurement by Pi - 3.1415 and that will give you the diameter of the cock ring (HAHAHAHA hooker math)- remember go bit bigger first or try rubber stretchy first save the hard materials for once you are sure of the size. Metal should always be 1/4" to 1/2" larger than rubber first try just to be safe. For shaft style just measure the erect shaft and use that measurement as the guide.
Which ones have you found that work the best?
some like rubber rings as they are less likely to get stuck and will grow and expand with the penis. I preferred a steel ring - I liked the cool of it at the base of my penis and partners remarked that they too found the coolness at the bottom of the stroke uniquely pleasing. Basically you have the right size if you can engorge the erect penis by kegaling 2 or 3 times and that will last a few 1 or 2 minutes.
What is the purpose for using them pleasure or to help keep mr.winky hard?
They were used often in pre-Viagra days. I knew many men that used them because their large dicks did not get hard, but remained semi-soft at erection and the rings made the erection more solid. I tried one because my penis was average size length wise but I always felt smaller than I would have liked in circumference. I found that as the blood flow was impeded my cock was engorged and the reported feeling from partners is that there was much better contact and pressure to the inside of their vaginas. It did not increase my pleasure per say as much as it increased my pleasure by being able to provide more pleasure to my partner. The biggest difference is that Viagra makes you hard - a cock ring gives you more girth as the extra blood swells the penis!
Can the cock ring be so tight that it can pop your blood vessels? Or does that suggest that it may be to small?
I have never heard of one popping blood vessels, but it could. I have heard of them getting stuck on and because they upon erection were too tight completely blocking blood flow which caused pain at the constriction area and if not removed could serious additional reactions. the solution as I understand it was to go to the emergency room and allow a doctor to insert a needle and draw out enough blood to allow the penis to go limp and the ring to slip off as intended. As long as you aren't trying to find the biggest erection you can possibly have you should have any issue using one.
Do you like the rubber or metal ones better? Why?
answered above steel .... sensation
I have had a few clients were (where) if I hold my fingers. firm around his winky I can keep him some what hard & still get him to cum.. But the cock ring does keep it firm.. which I think makes.them feel more comfortable.. Originally Posted by Dorthy_Monroe

Muahahah..
