Re: Eating cum
^Assuming the taste can vary from person to person, caused by changes in diet, lifestyle etc ...
And yeah, STD's can only come from an infected person, and can't be obtained unless you've engaged in unproctected sexual activity with said infected person.
I'd also like to point out that what you mentioned is a total paradox, because it's impossible to catch an STD from yourself by tasting your own cum, ingesting it would not cause you get one ... as you would already have it?! :S
