Katy Perry prefers her men to trim their pubic hair.
The 'Dark Horse' hitmaker insists she would rather it if the men she gets intimate with are well-groomed.
She shared: "If your teeth and nails are good, you're a candidate. If you can't clean under your nails and you want to touch me, forget it.
"And personally, the less hair, the better. I like a trimmed man but not completely waxed. I'm not into that f***boy look."
And the 30-year-old star also revealed there is a certain fragrance which always takes her back to memories of her first boyfriend.
She said: "If I meet a guy in the elevator who's wearing Acqua di Gio, I think of my first boyfriend. One of my favourite things about fragrance is the powerful memories associated with it."
And when it comes to herself, Katy loves a vanilla-based fragrance because she likes to "be edible".
She told Glamour magazine: "My signature scent now is, and always has been, a blend of vanillas. And I never spray it on my skin. I spritz and walk through--or levitate through. I like to spray it on my hair too.
"With Mad Potion, the two main ingredients are exotic vanillas and androgynous musks. It's definitely a sweeter perfume. I like to be edible. I want somebody to ... eat me."
