It sounds like marriage to anyone at this stage of your life is not the right choice. There are very few people that can live up to your expectations of sex almost daily on a consistent basis. Your wife is pregnant and her body is going through a lot of changes, not to mention emotional changes. After the baby is born it will probably be even worse for the first six months to a year. You are cheating on her with both men and women. If you even have sex with your wife occasionally right now you are risking the health of your wife and baby.

How are you going to manage the six weeks after she gives birth when she can't have sex? Obviously you married her out of a sense of obligation. Do you love her and want to be committed to her? Even if that means sex less than every day? If you can't be honest and can't commit then it's better to formulate an exit strategy and figure out how to co-parent.

Good luck!
