My fiancé and I have been into BDSM to varying degrees for several years, though it hasn't really become prominent until the last year or so (and even then mostly just bondage and light pain/humiliation). One of the challenges in our relationship is distance - we're both finishing up college about four hours away from one another. We love the physical and immediate aspects of BDSM (the things we can do when we're alone with each other), but I was wondering if anyone had advice for keeping the dom/sub dichotomy alive at a distance. I think it would make our physical encounters much more explosive if teasing and tension could be done for long periods of time over a distance. Any advice would be appreciated!
