lube

Any good wank-meister should be well versed in lube.  I have tried a lot and have found a hands-down favorite.

2 squirts of silicone-based Gun Oil provides just the right amount of slip and grip.  As long as you never remove your hand, things will stay slick for hours.  It costs a fortune, but has become a necessary staple for me.
The water-based I.D. Glide is not necessarily the best, but no water-based lube is.  I use it for any time that I am coming into contact with any silicone-based toys...DO NOT EVEN BREATHE ON A SILICONE-BASED TOY IF YOU'VE BEEN USING SILICONE-BASED LUBE...IT WILL DISSOLVE!
For anything going up my ass, I use Astroglide (not pictured.)  This stuff is available at Walmart and gets the job done.  Feels too slippery on my cock, but up my ass all that matters is a smooth ride.
