so ive been in a relationship with this girl for about 2 months now... and at first, sex was frequent and great. then, i eff'ed up my back (slipped disc or bad muscle pull; havent had time to go visit the doc), and for the past month i have no real desire to have sex. i mean ill be up and ready if the gf initiates, but if not, i dont bother. what the hell is wrong with me? (this is causing prob's - she thinks that its partly her fault, but its not) im just always busy with school, work, and trying to get into shape so I can get into the military. so im usually tired, or have too much crap to deal with.
