We don't fight per se - but I do get frustrated by sex less frequent than I would like - but the end result is some very hot sex - so in the end I wonder if it was worth the wait? Sometimes yes - sometimes no.
For us, I would say neither. When we have an issue we discuss it (using our mirroring techniques we've learned) until we both feel better. That works for me (and for him) and is healthier for us than either extreme.
I don't purposely withhold sex, but if I'm not feeling it, it's not happening. But we both think accepting sex and having it after means everything is forgiven. It tends to stay on the sweeter side those times.
