Will buy forever.
Works like a charm. No pregnancy so far! And no STDs to boot (although I'm not much worried about that with my wife). She claims the ribbed feature actually adds to her pleasure.
These do in fact make me last longer. It helps to keep the gel intact with yourself for 5 minutes or so for best results.
Just a disclaimer to other people who need these: there are other ways for many people. These may or may not work, and in my case they work way too well. Some research on Google or talking to a professional may get better results, if these don't work, or work too well.
Allows me to go from 2 seconds to 10 seconds. 10/10 would cum again.
