From personal experience I like Astroglide and Wet Platinum as a general lube, they're both waterbased and will wash off easilly. Flavored Wet is great too, no sugar, enough different flavors to choose from and it's really nice to assist in giving oral. One of the shops near me sells little sample sizes of different lubes. If you can find those, get a few different kinds and test them out before you go for the big size.
