Semen can change in consistency, depending on your diet, exercise, temperature, etc. You have to remember that this is from your body and can reflect what's going on with you. As long as you don't have any pain, it's fine. It must look scary if it's the first time you noticed a change, but you will live - unless you do have an STD, but you seem sure you don't.

There was one time I had not ejaculated in about a month, and then when I did it came out really dark.

Maybe your situation is similar, but it affects the consistency rather than the color.

I've had this too--usually when it's been a week or two between ejaculations. I assume it's just the semen coagulating. After it's happened, further ejaculates are fine.

It probably has more to do with how much water you drink and how often you cum than it does with anything else.
