Well, I am a 15 year old boy. Turning 16 in april. And yesterday, I was jerking off and I spermed blood with sperm. It was a mixture of both. I just jerked off today to see if it went away. And it didn't. I am getting worried. So I searched google and I found your site. I pee normally. Nothing hurts.. Color is normal.. Anyways, will my problem go away? Or will I need to see doctor

I really dont want to see doctur because them I will need to tell dad that I been wacking off to porn and I sperm blood. Also, it does not hurt when I sperm... I also used this oil thing to wack off 3 days ago. And I felt it go inside my uretha. Idk if this could be the problem

. Anyways I am very scared and I dont want to see a doctore about this.. But if I need to , then I will. (pretty embarrassing to tell doctor about me wacking off and crap)
edit
i am a virgin.. So I dont have aids or anything..
