I'm 23 years old and my current symptoms are low libido and sometimes it's hard for me to get an erection. When I ejaculate once, I feel no sexual desire afterwards, and I'm only able to ejaculate one time in a given day. I usually don't have any sexual desire for up to 2-3 days, or the sexual desire is very low. It also seems that my libido fluctuates a lot; like sometimes I'll feel like masturbating every 1-2 days, and other times I don’t feel anything for 5-6 days strait.

When I try masturbating with a lowered sexual desire, I always end up getting partial erections to no erections. I masturbate about every 3 days, or sometimes I wait even longer. The longer I hold out from masturbation the hornier I am and the better the sensitivity and hardness feels. If I drink up to 3 drinks or more of any kind of alcohol, I always have problems with erections. I have the hardest time getting an erection when I'm drunk and my sexual desire is a lot less too.

I've had a history of problems with my reproductive and urinary system; this includes phimosis, prostatitis, and cystitis. I had problems with phimosis when I was younger, which eventually turned into something way worse and now I'm where I'm at now. I used to have pain in my testicles after every ejaculation, and if I tried to get another erection that same day, it would be too painful to do. In addition I did have mental impotence at one point in my life, but that's all for the better now. My symptoms back then allowed me to masturbate once a month.. 

I also believe I have chronic fatigue and maybe some problems with my circulation. I'll have low energy for no reason sometimes and I won't be able to go to sleep. My hands and feet are always cold (feet more so) and I get cold and shivering faster than anybody I know when the weather is chilly. I've also been diagnosed with essential tremors. I don't know if any of this information helps.

Is it normal for me to have no sexual desire what so ever for this long, after masturbating just one time? When I have a hard time sustaining an erection I don't know if it's because of my lack of libido or is it something else that's wrong with me?
