Hi...I think I know a bit more than the last poster about this. There are countless kinds of lubricants out but ony a few that are good. What we want in masturbation, is the feeling of SEX. The things you both mentioned are not good enough. WET, is probably the best and most trusted. One called EROS is more expensive..but let me tell you....it's very "realistic" shall we say. The poster before me said Astroglide and that is GREAT, as well. One last thing..the lubricant's especially for masturbation..are all pretty lousy. The ones that say "J/O formula" (jack off) are too greasy. The ones listed above are the best. You'll see. If you are in a smaller town, you might have to get it on Ebay or something, in the "Everythng else" category. Good luck..or whatever.
Sin-cerely, Mr. Devine
