I completely agree with what you've said Pho. I have a strong suspicion that the reason why couples sex lives are failing is simply because they're lacking in the other parts. Sex is meant to strengthen a relationship and reinforce each mate's trust in each other. It is not however, something that should be depended upon soely to maintain a relationship as it'll only become a chore then. This is true of just about everything else in life that requires an immense amount of time and dedication.
Perhaps that doctor's opinion is true, but I am almost certain that it's true only for couples who confuse "lust" with "love" and mistake "hormones" for "passion."
I'd like to share with you all a light-hearted, but very accurate (in my opinion anyhow,) depiction of how a good relationship should be or perhaps just strive to be:
The links below are to a story-arc of sorts in an online web-comic by Scott Kurtz. Throughout the course of PvP, Scott Kurtz has done an awesome job at depicting the relationship between two of the main characters, Brent and Jade. I picked this one as it's the most recent, and I also feel that it does a great job at covering the "small things" in life that really matter.
