Blood in seamen, PLEASE help me out if you have any knowledge!

[Njik2005y]

Hi, I am an 18 year old male who discovered red and fresh blood in seamen about 3-4 weeks ago after ejaculation and there was no pain, fever, discomfort, or trouble with urine whatsoever before, during, and after ejaculation. When the second time I ejaculated, I experienced basically the same condition(but with less blood).  The 4th and 5th time I ejaculated there was ABSOLUTELY NO BLOOD OR PAIN(a week later)! However, in the 6th and 7th time after my abnormal ejaculation (another week later), there was thick, dark brown stuff mixed (blocking my way of ejaculating) with my seamen and slight pain with the head of my penis after ejaculation and again, I have no pain except that, no fever, and no trouble urinating whatsoever.

Some other facts:
-Fatigue(though I have been sleeping until 12:30 every night due to work)
-Less appetite(though I have decreased my hours of swimming again due to work)
-No sex partner
-Have been ejaculating since last year
-Have never experienced similar problems before
-Not all of my seamen are mixed with blood
-Nothing in my body is feeling abnormal

PLEASE answer my question and thanks a lot in advance! :)

might be that you are to rough with yourself if there's blood in the semen. give youself some time to heal and always keep in mind to use lube of some sort, either with a future partner or when by yourself. could also be a uti

Just to add, the blood was in seamen ONLY, not in urine at all
