I've had several lengthy periods when i didn't cum. First was on a business trip to Europe with another guy. He was a bit younger than me. We were friends and comfortable together. Had to room together for a little over 2 weeks. I was married he was single. We never talked about needing some relief but I know it was on both of our minds. Stayed really busy on the trip and exhausted when we got back to our room and up very early to start the day. I know I didn't cum the whole time and I don't think he did either. Looking back I wish i had brought up the subject and made an arrangement so we could both feel some relief. Got home and spent half a day in bed with the wife and made up for lost time!!
