Orange lumps in sperm

For weeks now I have had these orange bits in my sperm, sometimes tiny and unharmful and sometimes bigger and quite painful when ejaculating. Almost as though when it’s coming out it gets blocked and then forces itself out painfully. Doctors had no idea, clear of all infections following tests and iv been referred to a urologist.

They are hard to touch, almost like a stone but when squished they just turn to dust. Look a bit like crystals. Saw similar on here and they said issue was supplements and high protein but i dont take any supplements and i have quite a balanced diet, i drink a lot of water also.
