Okay, I looked this up online via google, and found lots of articles and some ask-the-doctor type sites that referenced clumpy semen. Apparently it's very common, NOT a typical symptom for any STD, and can be due to any number of normal biological variables (yes, very commonly dehydration), including temperature, diet, exercise, pH balance, etc.

STDs which affect ejaculation are most typically chlamydia, gonorrhea, and trichomonas. Those usually have a discharge, not at the time of ejaculation, that is malodorous, yellow/green, and can have a burning sensation with it, especially with ejaculation or urination. Prostatitis is infection or inflammation of the prostate gland, and usually has fevers and chills, pain with urination and sometimes ejaculation. Chlamydia, unfortunately, can be completely asymptomatic for both men and women, and can lead to infertility for women via scarring of the fallopian tubes. But none of these have clumpy semen listed as a presenting complaint. So, while STD testing is probably always a good idea, your clumpy semen issue is almost certainly not due to one, which is a good thing.

Anyway, sorry to blather on, and I'm glad your sperm is once again flying free and easy.
