PRINCE WROTE ABOUT SEX. SOMETIMES SERIOUSLY JUST ABOUT SEX, AND THAT WAS GREAT
I don't know if any Prince song isn't about sex, or at least doesn't contain some secret panel you can access to get to sex. Maybe "Money Doesn't Matter Tonight," sure, but even then that might be Prince reminding you that you're broke, and that's fine, because what you should be worried about is your soul. Your soul, by the way, lost its pants twenty minutes ago, and-- why yes, those are rose petals on the bed. For you. For you.
The rose petals might just be implied, or right around the corner.
