1 hour..... jk, umm i think the longest would have to be about 1 month without any solo love, but I wont count that because my gf at the time kept me honest :P but I would have to say 3 weeks when I went on a family vacation to visit relatives, entire trip I had to share a room...that was a couple years ago tho....in more recent times, just like Stylish-End, I was too sick to fap, and that was about 10 days (8 of those days were in a hospital...and its just weird to fap in a hospital...not impossible...thought about it but I just wasn't even able to move at that time).
