it just depends on what you consider to be a regular basis i wouldn't go on statistics cuz now a days in modern suburbia 1nce a week is enough for some people but not in my house hell no! i couldn't get through life with only that, i don't crave it like i use to but once its on its on! no two marriages are the same so don't go by what other people say and don't compare yourself to tencha and paco if 1 time is enough or 20 times is enough then you go on and be happy! and some women lose the craving for it and some will always want it it depends on the person and their sex drive!
