Don...It wouldn't affect your marriage, because you don't appear to care how marriage is defined.....man/woman...man/man...woman/woman..man/man/woman....man/man/ man...or any other combination you wish to propose....I suppose you could include your accordian/car /horse.....the mind boggles, but unfortunately for swingers like you, the vast majority of married folk are happiest with just a husband , a wife and couple of kids.
Oh I know it's so boring, but sometimes life's a bitch.
