I usually use some kind of lube, cut here, but no lube is just fine too. Depends on mood, if in for a long j/o session I like to have it all slick so I have used Astroglide, ky, udder cream, Crisco, any hand lotion that is around, cooking oils, Probe (which tends to need more every 5 or 10 minutes ), the lotion dispenser in hotel rooms and whatever else around.
