im 22 years old and ive been with the same man for 4 years. when we have sex its extreamly painfull for me, to the point where we cant continue, most of the time we cant even barely get started. My periods are also horribly painful, i cant get out of bed for two days!!! ive already had the surgery for endodemetriosis, and they found none. i just dont know what it could be, the doctors ive been going to now want to blame it on the fact that its in my head because they cant find anything, but its not in my head, this pain is very real and has been for three years now. any advice would be greatly appreciated.
