Edging

My boyfriend loves to edge me and I absolutely love it when he does... but I cant hold out of long. And by that I mean I have maybe 5 seconds before I cum if he keeps touching me. The only way to actually prevent me from finishing is if he stops touching me all together and just let's me sit for a minute before starting again and repeating the process. And that's fun and all but I want to figure out how to prevent myself from cumming all together without him having to stop touch me so does anyone have any tips?
