I'm pretty sure this could be an open ended question for both guys and girls, but I haven't tasted my cum since I was in middle school. Even then, it was only once, and it was barely a drip on the tip of my tongue. I remember it tasting like rotten eggs or milk, and I haven't tried it since then.
I've been trying to bring myself to try it again out of pure curiosity, but I chicken out every time, haha. Maybe I'll do it one day.
