Which Lube?
Yes lube, it does help with jelqin - but if you live with other people having a bottle of lube around the house is a bit odd - well not odd but other members of the house will think its odd, so I use a shower gel, although it does get a bit soappy and have to apply more each time it still works and once your done with your jelquin just put the bottle back in the couboard! and no one will take any notice of a shower gel bottle. not good advice I know but it might come in useful to someone.
OH YE - WASH your penis + balls after, DO NOT let the gel dry!!!! OUCH!!!!!
