Lately I have been having trouble keeping my erection during sex. A friend of mine was telling me to try this new product called Aspire36.. said he had crazy hard ons for like 2 days... said it was as good as like viagra or cialis. They have a free sample at Aspire-36 : How Long Do You Want to Last? but I wanted to see if any one on here had used it with success. I am much larger then my friend and wanted to see if worked for any one on here.
