Boy, where do I start. I have had low sex drive for the last year, and the year prior to that I don't recall having any issues. I'm only 19 years old, and can still remember all the energy I had about a year and a half ago. However, now I have very little to none. I eat healthy though, cannot stand for very long, legs feel like giving out most days - seeing a neurologist at the moment who doesn't seem to take me too seriously on that matter. The odd questions is: I have noticed during the summer that when I don't ejaculate for a period of 1-2 weeks, I don't feel tired anymore, my brain fog disappears, I have the energy to get through the day, and help out around the house, I can focus, remember, keep track of time, im in a great mood, really high self esteem, no anxiety at all, pretty much the way I was a few years ago. As soon as I decide to ejaculate and it's over, it's a matter of 5 mins that it all goes away, and im left feeling tired, sleepy, unable to concentrate or remember, weak, **** mood, a bit paranoid until 1 or 2 weeks pass, and i feel better again. Now my question is, I have urges, but I have to sacrifice them for weeks just to maintain my energy that help get me through everyday, and to be able to function like everyone else, so do I have low testosterone, or are my hormones just out of whack? It is a real big concern, because im only 19, and I've been to the sleep center because I thought I had a sleeping disorder, but I was only diagnosed with mild sleep apnea, and I'm sleeping with a CPAP machine now, with little improvement on my physical energy.
