What is the best lubricant to masterbate with? I have tried alot growing up, and I know other guys have too, but what have you found to be the best wehn you wan't something slippery? I have found conditioner to be the best, it stay lubricated and does not dry up, or soak into skin like lotion. Anything better? And no lubricants from sex stores, they seem to only work during sex, but still do not last long.
