Hello,
It can be due to Mondor’s disease or varicose veins. It is superficial thrombophlebitis of the penis. This is an inflammatory reaction to a clot within the vein. This subsequently causes blockages and dilation of the vein. It is typically painless, but can be painful. In studies, patients were noted to have thrombophlebitis after a prolonged sexual act with or without intercourse. It was described as cord-like thickening of the superficial penile veins.
Diagnosis can be confirmed by ultrasound. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.

What will his Ultra Sound results compare to though?
Answer: "the middle of the bell curve chart."
Testing someone --especially in a culture this variable-- only works if the person tested "calibrated" the testing apparatus themselves when they were healthy.
The guy above has a certain penile pulse rate (or whatever the detail is) and blood pressure _now_ when ill _for him_. But that tells us nothing about what his "rate" was when healthy _for him_ before the new symptoms.
The various tests we all do only work for those citizens who were in the middle of the "bell curve" chart and then when they became un healthy their stats dipped below (to the left of) the middle.
And then there is the phenom where--I believe-- the doctors don't care that certain classes-of-type have illness.
