I don't owned a chasity device at this moment but I'm trying to abstain myself from masterbating. I have the nexus G -rider toy, I've used it twiced and no spunk came out after using it. How long am I suppose to do it for and how frequently in a week? I've used it yesterday and today and nothing. But of course i stimulated my penis yesterday and ejaculated normally, am I suppose to let the cum buildup in my system for a week or so? very little of pre cum came out but thats it.
