Seriously, I don't trust doctors that say I am in great health but don't show me my test results. Too many just look for either the H or the L on the tests without looking for the subtleties and the borderline results.
Was this your regular doctor or a psychiatrist? Xanax for performance anxiety? I don't think so. That is for Panic Attacks and poeple who generally cannot function in everyday life due to their high anxiety and depression. It is certainly not for someone who simply goes soft during intercourse!
Dump that doctor and the pills and find yourself a male doctor and be honest with him as to what is happening. I'll bet he will prescribe an ED drug short term just to see if it resolves your problem. Then, he may order other tests. Keep us posted.
okay, we need some more info here. What meds are you taking or have taken? For example....steroids can cause you to not get a hard on and so can Xanax....dumb doctor. A lot is mental and your trying to make the big guy come to attention. Have you tried yohimbe, viagra or any hormone enhancement drug? Has she tried going down on you and voce versa?
