No reason to feel foolish; we've all been there and done that at some point. In my case I was exactly the opposite; I was sure I didn't have prostate cancer. But when my psa started going up my PA ordered an MRI. It showed a lesion, and even though I didn't think I had cancer I drove 300 miles to where I could get an MRI fusion biopsy so I knew they'd be able to biopsy the lesion. I fully expected it to not be cancer. Lo and behold, I had 3+4=7. Then I felt foolish when I reflected how sure I was I didn't have cancer. The important thing is to make the effort to find out early since prostate cancer is so much better to find early as compared to later. Best wishes.

Oh c’mon, man!! You think you’re the only guy who ever thought this way??
First, you’re told that ejaculation - no matter how you get there - is beneficial…then, they tell you that ejaculation raises your PSA.
So, of course you immediately abstain from sex in any form and pray that your evil ways will be forgiven and your numbers will drop.
I’m embarrassed to tell you how many times I’ve yoyo’d between these two extremes. 😆
