I have recently found that Nivea for Men aftershave balm does it for me.
I had finished shaving my cock and balls and found some in the bathroom and thought hmmm why not, so applied it, it was cold, smooth and made my cock all shiny and I was rock hard within 30 seconds so had a looooong glorious wank just rubbing it over the head, kept edging until after what seemed an age I was cumming like a fucking fountain, huge spurts of the stuff, hadn't cum like that since my teens, amazing stuff.:smile:
