Gotta love serial monogamy. Best of both worlds. I've had three relationships that were longer than seven years, and three that were about three years. So I've been paired up in years for just over half my life, but I also got to trash around and sow some wild oats. (One tequila, two tequila, three tequila, whore. LOL) The trashy times in my life were just as satisfying as the paired times but for different reasons.
It would be nice to pair up one last time for this final push to eternity, but at my age, a lot of the good ones are either taken or dead. haha!
