sweet balls...

So I've always heard that balls are sweaty and taste gross but today was the first time I ever payed attention to them. My boyfriend said he didn't want me to because he didn't think it'd feel good and he has hair and he just didn't want me to feel awkward. But I want to pleasure him in every way I can. So today I sucked and licked his balls. And he loved it. But the weird thing is that they tasted oddly sweet. We looked this up and apparently "testicles have tastebuds that can detect sweet flavors". But that wouldn't make them taste sweet. Idk. Maybe it's just me or maybe he put his balls in sugar this morning without telling me. Anyone else experience this? Here's a screenshot of the tastebud thing too.
