How random is the random guy? Only you know what you are comfortable with.
Try as I might, I just don't care for the taste of cum - my own or anyone else's. I can't really describe what it tastes like though, or what about it I find objectionable. Maybe it's the combination of salty and bitter. I know changes in diet are supposed to change how it tastes but there is some underlying commonality of cum that seems to have been present in that of those few guys whose cum I've tasted. So, I'm not a fan.
Although - and this is an odd corollary - if a guy shoots it directly down my throat, I find that hot and would swallow.
