Clear fluid leaking from penis

[Force101]

I had unprotected sex a little over two weeks ago, and about the next day or day after I seem to have acquired this slight leak of clear, odourless liquid from my penis. It mainly occurs after I urinate, but it feels like it's doing it a few times throughout the days and nights too. It's not a massive leak, like nothing is gushing out, but I can just feel it in there and it's quite annoying. There's also a very slight ache which comes and goes in both testicles. There's also no burning or pain when I pee or anything.

I should also mention when I had sex that I seemed to ejaculate fast prematurely on this particular occasion. I had a read around and discovered this can go hand in hand with seminal fluid leaks. Would it be seminal fluid?

I went to the doctor about a week and a half later and explained everything and he tested me for STIs and it came back negative. He also gave me antibiotics for Chlamydia, Gonorrhea etc just in case, but I'm still having this issue.

Help would be appreciated!

Typically most STD's will not present in a day.

Could be seminal leakage. It is a discharge and if the tests are negative, it's unlikely to be STIs. Does it make any difference how often you jerk off on the amount of fluid and how often it occurs?
