I second John in the second blood test, as the first will be your guide.
If there is a change from the previous one, higher that is, then I would ask for a DRE if not from that GP then if you have others at your surgery see if there is one which deals with men's health.
We actually only have two male GPs at our, one of whom is never available, the rest being women and I know my husband would not go and ask one of them to do a DRE
One of those female GPs doesn't even like looking in your ears so I can't imagine what her reaction would be to a DRE request !!
At the very least you should be getting a print out of your readings, both the new test and the previous one, then you have your own paperwork.
This shouldn't be a problem, we ask either the nurse or the receptionist for the printout and it has never been refused yet
We can't control the winds - but we can adjust our sails
If you do ask the GP to do a digital examination, make sure you ask AFTER he has taken the blood test. Pressing on the prostate to see if it feels normal can falsely raise the PSA level

In addition, before you have a PSA,
Ideally, you should not have: had an orgasm within 48 hours*, suffered a blow to your groin area, ridden bike or a motorcycle.
* Close to is apparently okay, so no need to abstain from all activity, but don't complete the journey.
Be content with your choice of treatment at the time you make it. Then make the best of every minute, every hour, every day.
