<human>: Can you provide a brief rundown of the text in within 3 sentences?

For two days, yesterday and today, while masturbating, (I do it once a day) the initial part has contained blood in it. The first day, yesterday there was a reddish hue and you could tell it was blood. Today it was a lot more. I have heard that bloody semen is often times a case of simply tickling the pickle a little too often. 

A brief medical background: 17 year old, and I do have 1 underdeveloped, but still present testicle. I have two, but one was caught in the nerves when I was being born and did not fully descend. I have been to doctors and it is not undesended and isn't a medical issue. 

I have also been having a slight pain in my rectal area right before relieving myself. I do not know if it could also be an irritated prostate. I'm also concerned in how I should let my parents know about this. Should I just tell them, or say during a wet dream I woke up and it was bloody?
<bot>: my semen is bloody and I don't know if I'm beating off too much or it's a real medical concern.
