Woods, who was benched for the first time ever in the Ryder Cup or Presidents Cup at Medinah, lost all three of his matches with Steve Stricker before halving his singles with Francesco Molinari after Martin Kaymer's win over Stricker in the match ahead had ensured Europe retained the trophy.
Reports in the US on Monday said that Woods sat down with Keegan Bradley, Jason Dufner, Webb Simpson and Brandt Snedeker and said sorry for not getting the points which would have given Davis Love's side an even bigger lead than the 10-6 advantage they took into the final day.
"I had an opportunity to earn three points in team sessions but I did not do that. It was tough," said Woods, who has won 15 and lost 17 of his 35 cup matches.
"Stricks and I went out there and tried to earn points for the team and didn't do that and it was frustrating.
"We had a four-point lead and we went 0-3. If we could have earned a couple of points it would have been a pretty good lead going into Sunday's singles."
Asked about the disappointment of suffering his sixth defeat in seven Ryder Cup appearances, Woods, added: "It probably did not set in for a few days because I had two sick kids to take care of. I was focused on them.
"Then I started to talk to my friends, guys on the team, and once it started sinking in, the position we were in and what had transpired, it got a little tough for a couple of days.
"I texted Freddie (Couples, a vice-captain) quite a bit and Stricks as well. Then like anything it's a tournament loss and you have to move on to the next event. We lose a lot more than we win in this sport and you learn to move on."
Woods was also asked if he would like to captain the US team in the future, the 36-year-old - speaking ahead of this week's Turkish Airlines World Golf Final - added: "One day that would be fantastic.
"It would be a huge honour, hopefully it doesn't happen in the near future. I would like to be able to play for a lot more teams but certainly one day when my career is slowing down or it's over, it would be huge to be part of a Ryder Cup from the captaincy side."
