If "I" was a guy, WHICH I'M NOT!!!
I'd say "A Good Swallow".........
It's really not that bad....
(although, there has been to known some is....eat your greens and garlic guys!)
Researched:Every guy's semen tastes slightly differently, but it is fairly clear that semen is affected by one's diet. It's hard to give you a specific answer, but apparently milk/dairy products, broccoli, cauliflower, asparagus can have an affect on semen taste, as well as onion and garlic (which obviously affects at least the smell of your breath heavily). However, is it really worth changing your diet, and does she really want to swallow it? Some girls really just don't want to; don't try to make/convince her to do something she doesn't want to do.
