These are common marital intimacy and sexual apathy issues. If the subject is ever brought up, it will usually be one person blaming it on themselves and not the other, mainly because the subject of sex in marriage is so sensitive that most individuals tread very carefully so as not to hurt the other — “We aren’t having sex like we did, it must be me.” Is it true some things are better left unsaid? Sometimes, but if it weighs on your ability to enjoy the marriage, and resentment is seeping in, you must bring up your concerns in a loving, compassionate, respectful and diplomatic way.
