I've never used any extensively, but we've tried once or twice and it just feels like an anesthetic for your penis. It's just another numbing agent that kills the feeling, but honestly it makes things less enjoyable for us.
We've actually used a spray, not a cream, and it does help somewhat.. but truth be told, I don't know if it's the spray or the condom that we have to use with it (condoms also help my husband last longer by deadening the sensation.)
What do you think about prolonging creams? Do they all just make a mans junk cold so he's less sensitive? And if you have any that you really like, what would you recommend?
All depends on which ones you get. Everyone is different. Its going to mainly depend on how your body reacts to them. I would try a few of them in sample sizes if you can get away with it. Find what works and roll with it. We went through quite a few before finding one that worked (The Shunga cream)
