I'm going to have to give the Lifestyles Zero a try. If I don't have a thin sensitive one I can literally go for hours without sufficient stimulation to erupt. I've tried a fair number and have had issues with breakage, constriction, slip-off and lost, etc. My current condom of choice is Beyond Seven and I get then at the Megaplex on 281. Very good feeling and secure. Numerous times I have paused to check it is still in place because it was feeling too good.
I do have to admit I had a good experience recently with a Magnum, but it was applied with some additional lubrication and a technique I'm unsure of as I was distracted at the time by another blonde. It was awesome, both shots. I'm pretty sure it wasn't the Magnums, but either the application technique or the company I was in.
