I have this condition and have also seen the forum you have posted. No one seems to know how to solve the problem. I’ve been seeing a psychiatrist that specializes in sexual dysfunction, but every medicine he has tried has just made things worse. He means well and wants to help, but I think we are really on our own.
I only recently realized that I have regular anhedonia too, not just sexual anhedonia. This means that I can’t get excited about anything really. Buying a new car or listening to a great tune on the radio does nothing for me. I also have a lot of trouble giving or feeling affection.
I’ve become obsessed with reading forums and researching this stuff online, but we’re really all in the same boat. There are supplements you can take that treat some of the symptoms, but we’ll never be “normal” until we figure out the root of the problem.
