I have the same problem with KY. As Tish says, you should probably just get a sample pack and try them all out. Astroglide is a great product, but they just came out with H2O. Just tried it last night and it was great. No burning, and just about felt all natural. You might want to look into that too. Happy Hunting. :)
There are many lubes out on the market, get small bottles of different kinds and try them out.
