If a guy tastes too bleach-like or has a strong flavor, I have found more water usually helps dilute the flavor. Other than that, like flame boy wrote, fruit helps. But that is over the long term, for tonight, I'd try some parsley tea... that usually gets rid of any funk within a few hours.
Weird, but I know one guy who has semen that tastes like vanilla, it is something I could literally drink, and he doesn't do anything special. :shrug:
