Hi, Guys, I'm just join the community and I'd like to share my story and hopefully I can acquire some feedback from you.

I suffered from a Concussion 2 month ago on 8 Oct 2009 playing basketball. I fell over sombody and the back of my head hit the ground. People said I was out for about 2 min. I went to The ER after return my consciousness. I stayed there for couple hours,but the Doc didn't give me any CT scan or MRI because he said I was responding very well. However, I went to doc again a week after and he gave me the MRI, and the result was negative. He said things should be fine I just need to rest. Even though things seem to fine after 1 to 2 weeks, I did suffer from fatigue and a bit feeling of vomiting but never did, and My motivation was down,too. However, things seem to get back after 3 weeks. But the only thing bothers me is that I feel i'm unable to perform sexual activity.
I would have a hard time to get a erection ever since my injury, and the quality of the erection was not very good, either. I have not had sex for two months and even I tried to masturbate, the respond was not very positive which makes me depressed.
So far the only anxiety I'am dealing is the sexual activity concerns, but other symptoms of typical concussion doesn't seem to exist to me. I don't know if My case is odd or there could be some specific damage to your brain that cause your low motivation to sex.
I would love to hear your experience and any suggessions toward my case, Thank you.
