I personally have only tried viagra. My wife and I both loved the effects it had on hardness. The sides were a little harsh though. Felt like my heart was going to explode for a bit, had to slow things up and calm down for a few. I totally agree with the cockring though. I have tried many different ones in the past, but my wife grabbed one at the local porn shop a while back, and its the greatest thing I have ever seen. It has three rings hooked together and it holds pressure in three different spots that result in an amazing increase in size, both length and girth, and hardness. I highly recommend this to anyone who has not tried it, whether you need the help or not. I get greater sensitivity out of it and much more intense orgasms/ejaculations. Just my two cents. Peace.
