Hi,
I am sorry to hear your news.
Please see my profile which is really similar to you and I got diagnosed at 42 so similar age.
I had my prostate removed, and whilst I don't regret that, I have had to have follow up Radiotherapy.
An important question to ask is whether you can have nerve sparing.
Younger men often have better than average recoveries so don't be too afraid of the ED statistics mine is 90% normal just a bit weaker.
Best of luck and lots of us are very happy to DM if you want to hear more detailed experiences.
Diagnosis and deciding on a treatment plan are by far the worst bit, way worse than the treatment for most of us so just know this is the worst bit.
Also remind yourself how lucky you are to catch this early.
Good luck
