In other words, if he doesn't go to the doctor and get this issue rlovesed you are going to roll out on him? :-/ This is an embarassing thing to deal with and men deal with it differently. First thing YOU need to do is communicate your concerns with him. Tell him how you feel about it and offer your full support. He can't help the fact that his prostate is enlarged, but he does have a say so about the meds. He needs to get his butt to the doctor and get his meds changed. If your relationship is purely sexual then it should just go ahead and end so he can take care of his issues. Based on your question and statement, it seems that is your main concern anyway. Maybe he can fiind someone who is willing to be there for him and offer their full support regardless of his situation.
