Purposely of course, wet dreams don't count.
I went about 6 days after I got circumsized when I was 18, I wanked with stitches not fully healed (thats how thick I am). I had sex two weeks later as well, when recommended that I should wait six weeks. I was on a drought, so Docs advice wasn't going to hold me back. In the end it didn't make a difference.
Not very long really but I am 24, so I bet as I get older and my libido declines I will be more interested in gardenning and watching countdown.
