I am having a very similar issue, but I think I see some connections to my behavior.
I am 64 and started strength training about a year ago. I have dropped quite a bit of weight and have made very good progress strength wise. I do weight training on Mondays and Fridays and (what I call cardio) on Tuesdays, Thursdays, and Saturdays. It seems that I have the blood appear sometimes the day after one of my cardio days if it gets pretty extreme. I feel no pain. It has nothing to do with urine or semen. I have experienced none of the described causes or exhibit any of the symptoms of most of the sites talking about blood from the penis...

I am thinking that it is either a burst capillary either in the urethra or somehow blood is getting into my bladder and draining. It definitely has something to do with my cardio days..

Cardio days usually consist of 20-30 minutes on the elliptical followed by a bunch of core exercises... flat planks, side planks, leg crosses, sprinter crunches... and by then I'm pretty spent...

There is not a lot of blood and it is usually very dark red.
