I think it depends on the situation sometimes fully naked may be sexier while some other times lingerie may have more sex appeal also depends on the girl
So yeah i like both just as much
For me if a girl is super fit with a tight bod, I prefer full nude to take in the beauty of hard work and genetics.
But if she has got a few flaws here and there, maybe nice big tits and ass but a little bit too chunky in the stomach, then I'd prefer lingerie
