I don't think this subject can be generalized about. Every person is different, every one of that person's partners are different, and you're a different person today then you were six months ago. That is a lot of variation. Some people's relationships are literally torture. Others can carry on two or three happy relationships at the same time and still get things done.
All you can do is follow your nose. Local optimization is your friend. If you think to yourself "gosh, my plan to live like a celibate monk is making me cranky and depressed", perhaps you need to change something in your life. (Get out of the office!) It doesn't matter whether or not (e.g.) other people are happier and more productive as celibate monks, or whether there is some Grand Unified Theory of Productivity that prescribes monkhood. Those people are not you, and that theory may not apply to you. Even the best theories of human behavior can only describe averages, and it's unlikely that you are average in every respect. Just because the average human walks on two legs doesn't mean that one-legged humans can't walk.
