Let me argue my headcanon about Valentino being intersex
This is the cecropia moth:
I'm not 100% certain that this is the moth Valentino is based on, but it's the closest match to his wing pattern that I could find.
The shape of the wings matches pretty well, plus we have the black and white lining of the wings and that the cecropia moth is a silk moth. Also, it's one of the few moths I could find that has red elements, and it's one of the largest moth species, which could explain Valentino's size. And, on the second picture is more clear – the antennas are pretty similar.
The cecropia moths also don't have a digestive system – they survive on the nutrients stored from when they were caterpillars. Once grown up, their only concern is to mate, which is pretty on brand for Val.
Now to the point – to find mates, the female moths release pheromones to attract the males. So, at the very least Valentino is producing female pheromones. Plus, in general, the females of a specie are the ones choosing their partners, and "he only sleeps with 10s and Vox", so he's pretty picky about who gets to be in his bed.
Do I think any of this is canon? Not one but. Valentino might as well just not be based on any actual specie and all that being a coincidence. But I still think it's pretty neat. Also, I think it would make sense on a character being so sex-centered to have both bits. It could be thematically read as his Hell curse – his design is so love centered that I'm 99.9999% certain the reasons of him being in Hell is sex related, even if you could argue that he got his drug smoke/saliva powers later down the line.
