My partner and I also go through somewhat routine "dry spells" when we're just too busy, or not home at the same time, or our minds are on other things. Sometimes we experience the same "awkardness" about getting back together that you described, RC. Once in a while, though, something different and interesting happens: the dry spell seems to break our sexual routine and we have "new sex" again. I wish I could figure out exactly what the conditions are that lead to the 'new sex' resolution of the dry spell instead of the 'awkard reconnecting' resolution of the dry spell!
...because public space really matters!
