All anxiety problems are dependent on the individual. Some can calm down more easily than others. I will tell you it's a whole lot easier problem to get over than ED from meds or surgery. I had it once for psychological reasons and it just went away when I stopped being involved with the woman I had the problem with when I was a young man -- there was obviously something about her that made it stick around though I don't think she caused it, so it wasn't a long term problem. So if you can just forget about it or talk yourself out of it or, say, meditate before having sex until the problem disappears, the brain will just forget about it and you'll be back to normal. But again, it depends on the person how easily an anxiety problem lasts so you can't generalize.
