Tried and only one week.... I could probly go two weeks but at the same time there is nothing forcing myself to go that long without sex or fap.. so why try? and being that im on this site a lot its hard to ignore porn altogether
20 days is my record. As time pass, I get boner without reason, my thought became perverted(even more than normal...like always). An urge to masturbate appear and become a torture.
On the other hand, after 20 days, when you finally give up, you come a bucket and it feel so good when you cum(like 3-4x better). Waiting give better orgasm and more cum...but take too long to get to that.
I think once I get past a week, I could probably go for quite awhile without fapping :) Sex, however, would be tough... But, I only get that on a regular basis when I have a gf, so I guess I can go for awhile without that as well.
