Is this a joke? Most unhappy married people I've known say they have sex like twice per year or not at all. That sounds unbearable to me... Not how life is intended, not healthy at all. I realize things change, but I would think if sex is happening less than once per month, and this goes on for more than a year, the marriage is pretty much dead. But I'm a young(-ish) never-married guy, so what I'm off.
Some of these replies don't sound all that bad... Relatively speaking anyway. I've known couples who didn't even like each other yet "stayed together for the kids" for years. Hard to know what is best.
