brother, the issue may not just be the medical needs she has been going through... when what the last time you took her out? most times (and this may not be your case) it stems from deep in her, frustrated, lack of forgiveness, too much stress and more that she is going though(on top of all the other things she is dealing with medically)
#1 - ask her on a date
#2 - dont even try to get physical with here till this is fixed or close to fixed
#3 - seek councling - you both go (tell her it is for you not her)
#4 - does she have a past w abuse (dont answer this) but look in to it, council shoud help if she does
#5 - bro, take care of your self in the shower or in the prone and tmoss love thread
... as for the trt/hrt you on now what are you numbers? that would be a good place to start - if your way high that might be a place to cut back some... but, if you numbers are right on and your just being you then what can you do???? well, you could get some tren and kill your sex drive (i am just kidding!!!)
