If I read your post correctly you are seeing a PCP not a urologist. If you PCP is experienced and you trust him/her discuss seeing a urologist because of your concerns.

My experience with this was when I was to have a PSA test I was asked not to ride a bike or have vigorus sex. You had the latter which my doctors and R/O said can affect PSA number. Also infections in prostate can cause PSA rise. Prostatis, inflamation in prostate, infections in prostate can also affect your PSA numbers. You have posted you have had prostatis in past, blood in urine in past, and now more blood in urine and your doctor diagnoses was prostatis.

Below 4 is normal PSA level. But PCPs, urologist. R/Os have told me it is more concerning the steady rise of PSA numbers. You are at 2 but have posted you have symptoms of protatis, sex prior to PSA test, blood in urine, and your doctor diagnosis of prostatist.

Discuss with your doctor all of this and asked what he recommends. Asked about increasing the recurring PSA tests. Discuss with your doctor about seeing a urologist. When I had rising PSA numbers my PCP put me on every 3 month PSA tests. And then asked me to follow no bike, no sex, report any infections, BPH, signs of prostatis, prior to PSA test.

I see surftohealth88 mentioning COVID (which you mentioned you could have had) and inflamation it can cause. Again if me asked your doctor about this also. Just try to get as much information you can and don't be shy about asking questions.
