“There are men and women whose spouses have cut them off sexually...easy for people w/o that problem to say stick with it. I feel for these people.” Very thoughtful opinion. To me, spouses that do that or use sex as a weapon to control or manipulate instead of for bonding, relief and the pursuit of happiness are guilty of an offense equivalent to adultery.
Marriage without physical affection and intimacy is just roommates with a tax deduction.
