http://www.amazon.com/Durex-Performax-Control-Lubricant-Pleasure/dp/B00070D16S/ref=sr_1_1?ie=UTF8&s;=hpc&qid;=1211593583&sr;=8-1I had sex with my GF using these.. .Terrible. She told me that she felt almost nothing from these, It also did something to her. I too felt a difference, and it was not for the better. And did I last longer... NO. Look for something else to try. Durex should not be making these.
