I'm not a doc, but it sounds like retrograde ejaculation.
You don't mention if your taking any medications for anything, but this is my experience with no cum.
I can sympathize, I'm 64 and married for 44 years.
I had a very active sex life with my wife and could masturbate always.
Probably a year to 2 years ago ago I developed
Benign prostatic hyperplasia (
BPH), due to an enlarged prostate which lead me to having urinary tract infections. My Urologist told me I wasn't able to empty my bladder completely and this is what was giving me the urinary tract infections.
My urologist put me on a drug called Jalyn which has done wonders for me, no more urinary tract infections. I also had a Urethrotomy done by my urologist, this is a procedure that opens up the meatus/opening to help with better urine flow.
Sorry I digress. Since I started taking Jalyn when I masturbate or have sex with my wife I have no ejaculate. I have the feeling of coming which is still pleasurable, but no cum. I do have from time to time some pre-cum or possibly ejaculate that will flow from my penis which is exciting, but not at the times when I have sex or masturbate.
From doing lots of reading about Jalyn and it's side effects I'm experiencing them for sure.
I have what is called retrograde ejaculation which occurs when semen enters the bladder instead of going out through the urethra during ejaculation.
The Jayln relaxes the neck of the bladder which in turn does not allow the ejaculate to flow out of the penis, but backs up into the bladder. This is not harmful, but takes the wonderful feeling of my cum flowing out of my penis.
The Jayln is indeed doing a good job for me in relaxing the neck of my bladder and letting it empty all the urine and not causing me infections.
Although I've given up the wonderful ability to cum as I did most of my life, but not having urinary tract infections is so much more important for sure.
I know I've gone on forever and I'm sorry. I didn't want this to be about me albeit I wanted to let you know that medications can certainly change the way we ejaculate and how our penis's respond.
I hope I helped in some small way and try to enjoy what you do experience, try to imagine not being able to cum at all.
Talk to your doctor maybe he can adjust your meds if your taking any to allow you to come more potently.
Good luck,
