Sorry to hear about the troubles. Of course, I can't tell you whether or not to stay on HRT, as that is a medical decision. But I can tell you that I have received many stories of men who have had venous leakage reversed from testosterone therapy, especially if the levels are raised high enough. Furthermore, the studies show the same thing and so does your own experience. This is because the testosterone can actually heal and rebuilt the tissues within the penis. However, there are fertility and many other decisions that you have to make with your physician though.
Personally, I agree with your doc that T in the 1100's is too high. One thing to keep in mind: testosterone therapy often leads to a higher percentage of free testosterone than is normal. And at those levels you can start to aromatize.
