My wife has been working out with weights now for about a year. She has always been dominant in the bedroom, and she has asked me to get slimmer (so I've been cycling and trail running, and not doing any weights). I was already fit, but I have really slimmed down. We are now both 5'7", 140 lbs. Because of the weights, she has become obviously stronger and more muscular than I am, particularly in the arms and in overall upper body strength. We seem to have an extremely solid relationship, but I am concerned that she will become less interested in me because I am smaller than her. Are there any other married couples out there where this type of match has worked out? (or not worked out - so to speak).
