Here's my story:
I am about 200 pounds and 6 feet tall and 21 years old guy. For as long as I can remember, I have felt very weak right after the ejaculation and it takes me days to get back my energy, 4-5 days. In about 7-10 days after last ejaculation, I feel completely normal and energetic. Seconds after ejaculation, weakness takes over my body. I feel like ALL the energy has been drained out of me and I have absolutely no strength left in my body. I become completely lethargic and weak. The only thinkg that I want to do is lie on the bed and keep eating and drinking (juices and milk) to get back my energy. If I ejaculate at night, I mostly miss college the next day because I am too weak to go. Sometimes I feel slight pain in my knees as well for a few hours right after ejaculation. I find it hard for a couple of days to go one floor up on stairs. Slowly slowly, the energy starts to come back and weakness starts to go away in a couple of days after eating good breakfast, lunch and dinner. In about 3 days, I am quite better. In about 5-7 days, I get much better and feel that I have strength. I can start doing little exercises too then.
I have asked friends and all of them say that they don't feel any weakness after ejaculation. They even go out to play soccer after ejaculating but I can't even think about walking 100 meters without getting extremely tired and fatigued till days after ejaculation.
I never had sex. I have experienced ejaculation by masterbating, getting a hand job, rubbing it on a girl's body. The after effects are the same no matter how ejaculation takes place.
I also get nocturnal emmissions. But they don't cause any weakness. I have had nocturnal emmissions many times but no weakness after it.
I have tried to find out a lot what is wrong with me. I asked on lots of health forums and no one seems to know what is wrong with me. I can't go to a doctor for this (don't ask why). So just yesterday I came across the term POIS and I thought maybe this is what's wrong with me. But I'm not sure.
So that was my story and now I would like the experts here to tell me if you think I have POIS or if it's something else.
Thanks!
