Where is less of an issue than when. I've been into edging for awhile, but it requires a significantly long period without interruption. Unfortunately, I don't have that luxury too often. When I do, I like to really stretch things out for as long as I can, lying back in bed, making myself comfortable with porn and lube, and really just making a whole experience out of it. However, when I don't have the time or privacy and I'm still pretty horny, I'm not above a quick wank in the shower just to take care of business. It's nowhere near as satisfying, but it does give me a much needed release at times.
