I think it CAN be truly satisfying and actually grow deeper and sexier with every year that passes.
I've been married for 3 years now, a lover with him for 5 . . . and things are hotter than they have ever been and i only see that improving as there are still at least a hundred things i still want to try
With our discovery of our mutual love of all kinds of porn and watching it together 3-4 times per week, expanding on our fantasies and new and different kinds of sex that we can have, the addition of sex toys etc. . . . we keep it fresh and hot everyday.
I feel like the possibilities are endless with what we can do together. That being said, we are both highly sexual people and are intimate 6-7 days a week at least once a day, so i think our matching sex drives really have helped us connect in the erotic arena of life.
I suspect that having similar sex drives and similar sexual tastes is the key to having a happy sex life when committed.
