many pros suggest that only sterile, water based lubes should be
used...other guys who have done it for a while just use a little
spit...have to suggest that only STERILE lube should be used....when
in doubt, throw it out!!! Cleanliness cannot be stressed
enough....sterile K-Y jelly is my choice...oil based lubes are not
advised, even if they are more comfortable for new sounders...urine
can't pass the oil-based goo out as easily as the water-based....if
comfort is what you're after, try to get some sterile Lidocaine jelly
(Rx only)...that stuff may be hard to get, but it is the best in the
world and worth every effort to obtain...
