Abstinence, Edging, and Denial Adventures

I'd like to increase the intervals between ejaculations and make the most of teasing/edging/denial and "get to cum? games" for the times when I do orgasm.

I last ejaculated over a week ago so now seems a great time to start. I decided no touching until I couldn't stand it any longer, which was this evening. Wanted to cum or at least edge some. I decided to allow edging as long as there were no interruptions. Cum not likely but not impossible either. Well..I got to enjoy a glorious 15 minutes or so of edging when something erupted, but probably not what you're thinking. A fierce thunderstorm unexpectedly erupted. I took this a my cue to STOP edging. So I was able to edge without cumming with a little help from Mother Nature. I did NOT cum.

Update: Now I've made it to the end of yet another week without cumming. Been doing a bit more edging lately, and it's getting harder and harder to stop in time without ejaculating. Incredibly horny would be an understatement!

UPDATE:

I haven't cum since Jan 31, 2013 and for several days now I'm desperately horny like hell too and want to cum so badly it's driving me to more intense sexual frustration than I thought possible. All I can think about is an orgasm. 22 days without ejaculating feels like my absolute limit. I had only agreed to 20 days, but then rolled the chastity bingo, which says my next chance to cum isn't for 19 more days! And even then no guarantee. omg I can't wait 1 more day, let alone 19 or more. Please let me cum...I really NEED to cum. I've never been this desperate to cum.

Overwhelming urge to spurt

Thank you everyone for your replies, guidance and feedback. I was extremely tempted to just go ahead and ejac last night. INSTEAD, I was able to get to the edge 3 times last night simply by setting a vibrator atop my zipper. But after that the risk of going over the edge and involuntarily ejaculating seemed too great. It seemed to help provide a slight bit of "relief" in some small way, albeit for only an hour or so. (Usually I have excellent control of being able to STOP my hand or other activity before any danger of cumming even after hours of edging and days of orgasm denial.) This time, 25 days' worth of pent up cum is really making my testicles feel huge. I so NEED to cum I want to shout! I'd have thought the overwhelming urge to spurt might have gone down a bit by now, rather than intensifying each day. Every night I feel like I can't hold back all the pent up cum any more.
