Whether it is me or my wife tugging on my penis, this is absolutely the best lubricant we have ever used for this purpose. It remains slippery, silky, & smooth, with minimal reapplication. It feels wonderful, & a little bit goes a long way! We found it to be a bit too slippery for intercourse, as it was too slippery for us to experience any substantial friction when inside the vaginal walls. I have a normal length penis, with girth in the 90th percentile, but her vagina has delivered 3 boys, so it is not quite as tight as it once was. For masturbation, this cannot be beat!
