Is it okay if I see blood in my cum ?

Well, few months back, I had this really weird kink or addiction whatever you wanna call, where I really was in jerking off so I used to hold out the sperm Unlike i wanted it to release so i use to jerk off when i felt like i am about to release i use to wait for couple of seconds and start jerking off again for hrs this continued. I used to hold it for like 5 to 6 hrs and then l eventually release it which gave me a crazy orgasm like crazy crazy orgasm

and one find day I was just doing the same thing around 5 AM after like 5 to 6 hours of holding the cum, this time I see this weird blood in my sperm, I don’t know if it’s okay or not, yeah, just let me know.
