A Really Simple Little Tip
I like to prolong a masturbatory session by 'edging' repeatedly, often while reading the many great contributions to Solo Touch.
The protracted nature of these sessions means that even though I produce plenty of pre-cum, it still seems to dry out all too quickly, generating stickiness, rather than serving as a lubricant. My idea was to have some warm water near to hand so that I can avail myself of few drops, whenever the need arises. It works a treat and I urge you to try it, if you have a similar problem.
