I have asked this question to both my RP surgeon and GP - neither has had a satisfactory answer. I had laparoscopic RP in late August 2023. I had no other treatments (radiation/hormone therapy, etc. - as cancer was contained). Had urinary tract infection during preceding month (probably when catheter was in). Was resolved with antibiotics. However, I have had penile sensitivity/pain pretty much since surgery. It is not 10/10 pain - but it is an awareness. It is in no way "arousing". When I squeeze (anywhere from tip to base there is pain. Sometimes just pressing on the tip with tighter clothing/underwear/bike shorts it elicits pain. I know the urethra is cut during surgery and perhaps this has something to do with it. I have been doing aggressive kegel exercises since surgery - usually 3 x/day. I have also been doing red light therapy on perineum (as it has also been sensitive/painful to direct pressure). Sometimes I think I have a UTI again because of the pain - I have had myself checked twice for it - but was clear. I have continence about 90% under control. I am using sildenafil and taladafil (?) as part of rehab program for ED. Blood flow to area also causes sensation of pressure and a sense of moderate pain. All this to say, I do not have an answer - but I can identify with your symptoms. I plan on re-broaching the subject with my GP next month.
