Do you know any long lasting lubricants that dont dry out quickly?

I've heard great things about astroglide, though I've never tried it as I don't think it's available around here... I've never seen it anyways. DON"T use vaseline. it's horrible for you as it's made out of petrolium. That stuff is hardly good for anything! Don't use anything like olive oil or baby oil (or vaseline) that people are suggesting. Find one that's MADE for .. go to an adult shop (like stag shop or sin city), they usually have little sample packs of lube for 50 cents or so.. Pick up a bunch and find one you like.. then you can buy a big bottle of it.
