Actually, i have went for 3 weeks without cumming only it was not by choice, so I guess that dont count. I had a curcumsision procedure done, and I was told not to have sex for 6 weeks. The first 2 weeks were hell as the stitchs poked into my skin and moved around every time I moved, so any contact with the penis was no way going to happen. i did however eat pussy like crazy during that time which built up a huge urge to cum. One night I ate for almost 4 hours. Really! So at the end of week 3 I was feeling brave enough to try getting some very slowly. All my stitches had disolved by that point but I was still afraid of ripping my skin apart where it was stitched. I slowly went into my wife and went deep and just moved in and out about an inch or so. Finally after just a minute or so I came so hard she jumped and I even felt it shoot inside her and bounce back on my dick head. I came buckets and have since never even came close to that amount since. I try to abstain just to see how much I can build up, but without any physical reason holding me back, I just cant go to long.
