I've never really used lube when I jerk off. Once or twice I recently tried a few drops of baby oil and liked it, so I decided to go out and buy some "real" lube to try out. I went with Astro Glide and was pretty disappointed. It starts out ok, but turns dry and sticky a few moments in. Can anyone recommend a decent lube? Ideally something that's easily available in a drug store... Thanks in advance.
