Your Wife Just Found Out You're Having Gay Sex!
 

Dear Abby has some advice today for the wife who finds out her husband is having sex with men. For me, in a situation like this, the issue is of course not some revulsion over gay sex or being bisexual. Instead, it is about being dishonest with someone whom you pledged to do otherwise. Sorry, gentleman, but a vow is a vow. If you want to change the terms of your vows, that is the healthy solution and, no, that need not mean ending your marriage. But your wife deserves to know the honest truth about your life.

The principle problem in a situation like this is the loss of trust. If a married couple have an open relationship (incl. sex outside the marriage) in a common agreement, fine. If you swore to "forsake all others", that means outside pussy AND dick are verboten. Your word, your personal honor is what is at stake. If you can't resist the urge, talk to your partner. If they are not agreeable, you have to decide whether to continue the marriage or split to pursue your carnal desires.
