Long time DN player here who is not Lexil and can confirm from many years of playing from this canon that L's sex appeal is a thing. LightxL was like the biggest ship back in the day maybe it's because he's so weird and unobtainable idk but I was a Light and it's more psychological than it is physical, from my perspective

Everything in DN is a challenge. Even sex which is totally not canon but the literal thing of rp is to make your chars 3D and go beyond stupid anime tropes
