I Have A Question About My Ejaculate.. Looking Back In

I have a question about my ejaculate.. looking back in time, probably around late middle school/early high school it used to be what I presumed was normal (some what thick liquid). I’d say since late or mid high school till now (junior in college) it’s changed. When I ejaculate now it seems very watery and contains clumps, they don’t hurt but I can feel them. I’ve read quite a few things about this and most say it’s normal. What’s odd to me is that not long ago it was back to the type that i presume was normal but it changed again to watery and clumpy? I’m fit, I weightlift 5x a week, I’d say I eat a pretty high protein diet compared to an average person. Sexually active with my girlfriend. Should I consult a local doctor about this issue or is it nothing to worry about?
